Beijing Evergreen Science & Technology Co., Ltd. specializes in design & development of ASIC LD drivers and manufacture of ASIC driven LD modules. With professional expertise of laser diode, ASIC design, IC manufacture & test and innovative ideology, Evergreen has developed a series of advanced ASIC LD drivers with: accurate Automatic Power Control (APC), low operating voltage, wide operating current range, multi-integrated-protections against over-current, over-temperature, transient, monitor failure, ESD and reverse polarity. In addition, the compact size and durable structure will also support fail-safe LD operations.

With advanced ASIC LD drivers and skilful module manufacture engineering team, Evergreen has developed cost-effective LD modules with high performance.
Randomly sampled LD modules have been put in working state and supervised by 'EON Beijing Development Center'-the well- recognized notary organization in the LD industry. As of Feb 22th, 2006, the modules have been continuously working properly for 22 months and withstood more than 10, 000, 000 'ON/OFF' electrical triggers. This amazing high lifespan means 'Zero Maintenance for the 1st Two Years' to clients. It dramatically reduces the expensive after-sales maintenance costs.

Evergreen's ASIC LD drivers as OEM/ODM parts have begun to change the operational structure in the LD module industry. ASIC LD drivers require less manufacturing space and smaller assembling workforce. It will replace the current handcraft process of individual LD modules. In recent years, the system LD module end-users have begun to recognize LD driver as equally important as LD itself to guarantee LD module quality and performance.
