The Optoelectronics Company has rolled out a red laser diode that can replace large, expensive and wasteful He-Ne gas lasers. The Oclaro HL63163DG supplies 100mW single-transverse-mode optical output power at 633nm in the visible wavelength band. As highlighted by the company, the laser diode possesses the essential performance characteristics for biomedical and industrial applications that were only achievable using He-Ne gas lasers.

"We expect to see the HL63163DG laser cannibalise the He-Ne gas laser market as we have succeeded in reducing the size of the laser and lowering power consumption without compromising on the performance required by the biomedical, inspection and measurement markets," said Takayuki Kanno, Oclaro Japan president and GM of the Modules and Devices Business Unit. "A semiconductor laser solution was long overdue and Oclaro was able to overcome the design challenges to produce a sophisticated and efficient laser diode capable of delivering a high power 633nm beam," he added.

Building on advancements in laser technologies, the GaInP laser diode was designed to operate with a low power consumption of only 0.4W in a 5.6mm TO industry-standard package with TE mode oscillation. The device has a low operating current of 170mA (typ.), threshold current of 70mA (typ.), operating voltage of 2.6V (typ.) and LD reverse voltage of 2V. Operating temperature is from -10 to 40.

The laser diode has been in full volume production since January 2014. Samples for testing are available upon request.
