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.

Photonic Products, the UK opto-electronics device manufacturer and laser diode specialist, has expanded its range of laser diode modules with the near-infrared PM606-P Photon laser module which uses the first 705nm semiconductor laser diode from Opnext. This is an innovative laser diode module; a lasing wavelength of 705nm is totally new to the market.
The PM606-P Photon laser module is primarily designed for use in low level laser therapy, biometric sensors, fluorescence sensing and other applications which benefit from the laser module’s high reliability, low operating current requirement, and high output power. It is also ideal for energy-efficient, low-power optical measurement applications.

At the 69th Autumn Meeting of the Japan Society of Applied Physics at Chubu University in Nagoya, Japan next week (2–5 September), Tokyo-based Sony Corp will present the development of a high-power, short-wavelength red laser array diode incorporating a 2.5cm heat sink, making it suitable for use as a light source in projection devices.
For red semiconductor laser array diodes to be used in projection devices, they need to deliver high brightness, high efficiency and room temperature operation. The laser array diode achieves an oscillation wavelength of 635nm, generating brightness levels 1.6 times that of conventional 645nm red semiconductor laser arrays (developed by Sony in 2005), according to the firm.

Edinburgh festival: Trip the laser light fantastic
An Australian company sets out to dazzle, and Steve Reich gets a Belgian makeover.
Chunky Move: Mortal Engine
Edinburgh Playhouse
Rosas: Steve Reich Evening
Edinburgh Festival Theatre
Two highly challenging dance works at the Edinburgh International Festival last week looked in some ways quite similar - throbbing, minimal music, small groups of contemporary dancers trying to create new relationships between sound and movement - but they had diametrically different impacts. One felt like an assault, the other almost painfully cerebral.
Australian dance company Chunky Move gave the European premiere of its work Mortal Engine, which uses digital technology and infra-red-sensitive cameras to create dazzling and disturbing effects of light and movement. I can’t begin to explain the technology, but it’s obviously all very cutting edge, created by a German computer engineer whose video cameras follow the dancers’ movements, apply algorithms to them in real time (in the space of a 50th of a second, apparently), then use these to create lighting effects around them.

This innovative laser diode from Opnext offers the highest optical output power on the market at a visible lasing wavelength of 642nm. It supersedes Opnext’s HL6366DG series high power red laser diodes (642nm, 90mW). Opnext’s technology breakthrough was achieved with a new development process, a new waveguide structure and optimised structural parameter.
With its high output power providing exceptional clarity and visibility, the Opnext HL6385DG laser diode is ideal for use in laser display applications, such as laser light shows. It also offers the brilliance of a light source needed for next-generation miniature displays in the industrial and medical industries.

Open wide: Laser treatment that takes the drilling out of fillings
It is a sound to strike dread into the heart of even the bravest patient.
But the squeal of the dentist’s drill could soon be a thing of the past, says Emmanouel Koloutsos.
The London-based dentist has become one of the first in Britain to offer ‘pain-free’ laser fillings.
He can prepare a tooth for filling in the same time as using conventional equipment, but with almost no need for pain-killing injections - and crucially no drill.
Lasers are used more widely in other areas of dentistry, but until recently have not been powerful enough to cut through hard tissue such as enamel and bone.

An airborne laser weapon dubbed the “long-range blowtorch” has the added benefit that the US could convincingly deny any involvement with the destruction it causes, say senior officials of the US Air Force (USAF).
The Advanced Tactical Laser (ATL) is to be mounted on a Hercules military transport plane. Boeing announced the first test firing of the laser, from a plane on the ground, earlier this summer.
Cynthia Kaiser, chief engineer of the US Air Force Research Laboratory’s Directed Energy Directorate, used the phrase “plausible deniability” to describe the weapon’s benefits in a briefing (powerpoint format) on laser weapons to the New Mexico Optics Industry Association in June.
