Photonic – New laser for high-power RGB white light sources

Nov 10 2008 - Switches, Relays & Onboard [More Switches, Relays & Onboard Articles]

Introduced as the world’s first 642nm, 150mW, single longitudinal mode semiconductor laser diode with TE mode oscillation; the Opnext HL6385DG, is now available from Photonic Products.

The innovative laser diode offers the highest optical output power on the market at a visible lasing wavelength of 642nm. The 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 HL6385DG laser diode is fast becoming the industry standard red laser diode for use in laser light show systems, replacing less intense 660nm diodes.

The device itself is a single longitudinal mode diode with low aspect ratio (<2:1) which, coupled with the small emitting chip size (3×1µm), allows efficient combination of multiple diodes in high power RGB white light sources, says the company.
