635nm Red Laser Diodes Improve Energy Efficiency In Industrial And Medical Applications

Photonic Products, the UK optoelectronics device manufacturer and laser diode specialist,
announces the introduction of two new 635nm, 5mW laser diodes from Opnext, Inc. The
operating current on these diodes has been decreased by 50 percent, resulting in extended
battery lifetime and lower power consumption without compromising their 5mW optical output
power. Their aspect ratio is also improved from 3.8 to 3.1.

They are suitable for use as light sources in laser levellers and measurement equipment, and
ideal for medical and display applications.

Supplied in a 5.6mm package with 1N (HL6354MG) or 3P (HL6355MG) type common cathode
pin configuration, the single longitudinal mode laser diodes have a typical operating current of
27mA, a low threshold current of 18mA, operating voltage of 2.2V, monitoring output current of
0.4mA, laser reverse voltage of 2V, PD reverse voltage of 30V and TM mode oscillation at a
visible wavelength of 635nm. The operating temperature range is 0 degrees Centigrade to +50
degrees Centigrade.

The Opnext HL6354/55MG laser diodes are pb free in compliance with the RoHS Directive.
