Product and Technology Ushio releases new 600mW 405nm laser diodes
2020.09.01
Ushio Inc. is releasing new violet laser diodes (LDs) HL40113MG and HL40115MG for 405nm.
The latest additions to Ushio’s violet LD product line-up have 600mW of output power (CW). Although HL40113/115MG share characteristics with existing Ushio LDs, they offer significant improvement in wall-plug efficiency, slope efficiency*1, and overall lifetime.
For comparison, HL40113/115MG offer a seven point increase in wall-plug efficiency*2 from existing Ushio LD HL40063/65MG (the WPE values are 28.6% and 21.4%, respectively), further reducing power consumption and heat removal requirements. HL40113/115MG also provide an 18% improvement in slope efficiency compared to HL40063/65MG, creating advancements for overall system optimization.
HL40113/115MG additionally improves the LD lifetime by 40% in comparison to HL40063/65MG. This substantial development enables longer-lasting, more productive, and more cost-efficient laser systems, which are optimized for applications such as laser direct imaging (including photolithography and PCB manufacturing), as well as many bio-medical and life science fields.
*1 The efficiency of the optical light output power against the input current.
*2 The energy conversion efficiency with which the system converts electrical power into optical power.
