Description
1. Low current noise RMS<1uA.
2. Capable of delivering output voltages up to 23V, suitable for driving virtually all small-power lasers, including DFB (Distributed Feedback) lasers, VCSELs (Vertical-Cavity Surface-Emitting Lasers), ICLs (Interband Cascade Lasers), and QCLs (Quantum Cascade Lasers).
3. Able to provide output currents up to 1A, thus able to drive a wide variety of small-power lasers like DFBs, VCSELs, ICLs, and QCLs.
4. Maximum output current can be limited through a potentiometer, ensuring the safety of the laser device.
5. Supports remote control for enabling/disabling output and monitoring the output current.
6. Offers ultra-stable output current bias and allows for current modulation.
