SANYO laser diodes, has announced that, due to the recent merger between SANYO and Panasonic, SANYO will end production of its industrial red and infrared laser diodes at the end of September 30th 2010. The last time buy date for all affected product lines will be March 31st 2010
In order to fully support its SANYO laser diode customers, Photonic Products has negotiated an agreement with SANYO whereby it is able to guarantee order coverage for up to two years, providing final orders are placed by March 31st 2010
Photonic Products will also source and recommend suitable alternatives from leading manufacturers which will provide equivalent performance and reliability at a comparable price. During the transition period, the company’s engineers will work with customers to evaluate and approve alternative laser diodes to prevent disruption to production schedules and minimise any inconvenience.
SANYO will continue to manufacture 405nm blue-violet laser diodes which are available in industrial strength up to 85mW optical output power and with the stability required for critically demanding industrial and medical applications. Photonic Products will continue to distribute SANYO blue-violet laser diodes.

The near-infrared laser pathway into the cell culture plate, traced by visible laser for photo.
Researchers at UC Santa Barbara have developed a new way to deliver drugs into cancer cells by exposing them briefly to a non-harmful laser. Their results are published in a recent article in ACS Nano, a journal of the American Chemical Society.
“This entirely novel tool will allow biologists to investigate how genes function by providing them with temporal and spatial control over when a gene is turned on or off,” explained Norbert Reich, senior author and a professor in the Department of Chemistry and Biochemistry at UCSB. “In a nutshell, what we describe is the ability to control genes in cells –– and we are working on doing this in animals –– simply by briefly exposing them to a non-harmful laser.”
The scientists used cancer cells from mice, and grew them in culture. They then introduced gold nanoshells, with a peptide-lipid coating, that encapsulated “silencing ribonucleic acid” (siRNA), which was the drug that was taken up by the cells. Next, they exposed the cells to a non-harmful infrared laser.

This laser payload sends pulses of infrared laser light towards a strip of lunar surface and detects and analyzes the reflected portion of that light.
Now that the MIP is on the lunar surface, further mission objectives are being realized. Two days after the MIP landed on the Moon, the lunar laser ranging instrument (LLRI) on board India’s first unmanned spacecraft Chandrayaan-1 was switched on.
ISRO stated in a statement “The instrument was turned on when the spacecraft was orbiting over the western part of the moon’s visible atmosphere. Initial data indicated the instrument’s performance is normal.”
This laser payload sends pulses of infrared laser light towards a strip of lunar surface and detects and analyzes the reflected portion of that light. The wavelength of the light used in this case is 1,064 nm. This instrument also accurately measures the altitude of the spacecraft above the lunar surface and the Moon’s surface features.

A fortunate ancillary benefit of the massive investment in telecommunications sources has been in other areas requiring tunability at similar wavelengths such as measurement and fiber-optic sensing systems.
STEPHEN KREGER
Before the peak of the telecom investment bubble, tunable lasers were seen as a key network component that would increase network reliability and reduce costs of spare lasers. Startups like Iolon and Agility easily attracted investments in the tens of millions of dollars at each round of funding; even corporate giants such as Intel poured money into research and development.
But the telecom tunable laser boom did not materialize as planned, mostly because of rapidly declining costs and improved reliability of arrays of fixed-wavelength distributed-feedback (DFB) lasers.
After years of consolidation among tunable laser manufacturers, a number of vendors still survived, in part by taking advantage of higher margins afforded by integrating their products into test equipment, such as Luna’s optical-backscatter-reflectometry technology, and by tailoring their designs and lowering costs for applications outside the telecom market.

It’s a treatment that’s been studied for more than 30 years. Now this non-surgical therapy has been approved by the FDA. Cold Laser therapy is becoming widely recognized by professionals in healthcare, sports medicine and by chiropractors.
Those who offer the treatment say the red and near infrared light over injuries, lesions, burns, pain, inflammation and other disorders stimulates healing within those tissues. It has also been found to be an extremely successful treatment for alcohol & drug addiction, weight control, and smoking cessation.
Barbara Benedict had a constant nagging pain in her shoulders that she said made everyday chores impossible.
“To turn your neck and to turn the car wheel was a painful motion. I had a terrible time bending down and tying my shoes,” said Benedict.
Benedict was diagnosed with frozen shoulder, a condition that limits a patient’s range of motion. After traditional treatment options failed, Benedict tried cold laser therapy.

Photonic Products, the UK opto-electronics device manufacturer and laser diode specialist, is delighted to be the authorised distributor of the first 705nm semiconductor laser diode from Opnext. This is an innovative laser diode from Opnext; a lasing wavelength of 705nm is pioneering and unique, totally new to the market.
The Opnext HL7001MG/HL7002MG laser diode is designed for use in biomedical applications such as blood analysis and endoscopy which benefit from this infrared laser diode’s high reliability, low operating current requirement, and high output power. The lasing wavelength of 705nm at 50mW offers high permeability for living tissue and low absorption of haemoglobin and water.

Which sounds like a better way to make the roads safer: rescind drivers licenses from people who are very old and have failing vision, or create a fancy system with lasers to allow them to keep driving?
If you answered the latter, you’re in the same camp as General Motors. They’re hard at work on a fancy new windshield that uses lasers, infrared sensors and a camera to make it easier for your decrepit old granddad to see just where the hell he’s going.
The system projects a laser on the windshield to highlight things that you should be noticing.

The first passenger plane equipped with a system to repel shoulder-fired missiles successfully completed its flight, a British defense and aerospace company announced Wednesday.
The JetEye infrared missile-defense system was tested on an American Airlines flight that took off July 11, according to a statement from BAE Systems.
The plane flew from New York’s John F. Kennedy International Airport to Los Angeles International Airport in California, the company said.
The JetEye system works by detecting the heat-seeking missiles and then firing a laser, which diverts the missile.
American Airlines refused to make the system mandatory on all trips but agreed to cooperate with the tests.

Low-cost infrared night-vision systems could soon be a regular feature in cars thanks to a new EU project.
Six of Europe’s leading companies and research establishments have joined forces to develop a prototype low-cost infrared night-vision system that can accurately resolve pedestrians and animals on the road. The project is called ICU, which stands for Infrared Imaging Components for Use in Automotive Safety Applications.
The plan is for the prototype infrared imaging system to provide high contrast images of warm (living) objects that are completely independent of ambient light conditions. The project partners believe that if such a system were to be used in cars, it would reduce both the number of accidents involving pedestrians, cyclists and animals as well as the death toll and the number of people who are seriously injured.

Scientists are carrying out a laser scanning survey of Djosers Step Pyramid – Egypts oldest pyramid complex, in an attempt to create its virtual three-dimensional model.
The Step Pyramid was built during the reign of King Djoser of the Third Dynasty (2687-2668 BC). It is the first pyramid in Egyptian history, and the earliest stone structure of its size.
The scanning of the pyramid is being done with the help of the Zoser Scanner.
Carried on the backs of three professional climbers as they grappled to descend all four faces of the pyramids six gigantic steps, the Zoser Scanner records data at the exceedingly fast rate of 40,000 points per second using infrared signals to gather coordinates and elevations of thousands of points on the monument.
