NEW : Ushio releases two 600mW 405nm violet laser diodes

Ushio. has announced the release of two new violet laser diodes, HL40113MG and HL40115MG, emitting a wavelength of 405nm. The latest additions to Ushio’s violet laser diode line-up have a continuous wave (CW) optical output power of 600 mW. Although HL40113MG and HL40115MG share characteristics with existing Ushio laser diodes, they bring several significant areas of improvement. These include wall-plug efficiency (WPE), slope efficiency and an extended overall lifetime. They are optimised for applications such as laser direct imaging, including photo-lithography and printed circuit board (PCB) manufacturing as well as many bio-medical and life science fields.


NEW : Ushio HL40071MG 405nm 300mW Laser Diode

The Ushio HL40071MG is a single transverse mode 405nm laser diode which offers 300mW optical output power in a 5.6mm package with typical optical and electrical characteristics, (Tc=25 degrees C, cw), of 50mA threshold current, operating current of 280mA, operating voltage 6.0V, 6 degrees beam divergence parallel to the junction, 15 degrees beam divergence perpendicular to the junction, laser diode reverse voltage of 2V and operating temperature of 0 to +70 degrees C.
