Ushio releases new 600 mW 405 nm violet laser diodes

Ushio Inc. (Japan) has announced the release of two new violet laser diodes (LDs), HL40113MG and HL40115MG, emitting a wavelength of 405 nm.

The latest additions to Ushio’s violet LD product line-up have a continuous wave (CW) optical output power of 600 mW. Although HL40113MG and HL40115MG share characteristics with existing Ushio LDs, they bring several significant areas of improvement. These include wall-plug efficiency (WPE) [1], slope efficiency [2], and an extended overall lifetime.

For comparison, HL40113MG and HL40115MG offer a seven point increase in wall-plug efficiency over the existing Ushio LDs HL40063MG and HL40065MG (the WPE values are 28.6% and 21.4%, respectively), further reducing power consumption, and heat dissipation requirements. HL40113MG and HL40115MG also provide an 18% improvement in slope efficiency compared to HL40063MG or HL40065MG, creating advancements for overall system optimisation.

HL40113MG and HL40115MG additionally improve their LD lifetime by 40% in comparison to HL40063MG and HL40065MG. Ushio’s persistent development of its laser collection enables longer-lasting, more productive, and more cost-efficient violet laser systems. These specific laser diodes 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.
