We offer off-the-shelf and OEM ultrashort pulse generators and laser drivers. The PL1.0 is an efficient and practical short-pulse and high driver current laser diode driver in a compact OEM package. It generates 2ns very short pulses with pulse repetition rate arbitrarily settable from 400-100kHz. It’s build-in pulse generator eliminates the need for external signal generator that is required by most of the pulse laser drivers in the market. It outputs up to 1000mA peak driving current, suitable for driving nowadays butterfly-packaged or TO- can packaged laser diodes.
The PL1.0 is specially designed as the seed laser driver that will set the performance of laser systems at the most suitable parameters for laser micro machining and other applications. It’s pulse width and repetition rate are designed to match to the scan-mirror commonly used in the laser micromachining machine.
We design and manufacture custom LD drivers to the specs of your choice. Pulse width, repetition rate, driver current, and control interface can all be customized to fit your needs.
