Laser Controllers/Drivers
Our laser drivers/controllers are designed for driving laser diodes with high stability, low noise, and/or high power efficiency. These are some of the functions they provide: laser current setting and monitoring, control loop good indication, driving mode indication (for dual mode versions), stand-by, and shut down. Due to their high efficiencies, most of our laser drivers/controllers can work without heat sinks. In addition, our laser drivers/controllers have complete metal shielding, which presents the laser drivers/controllers and other electronics from interfering from each other. We have full line of laser drivers/controllers: low noise low current, high efficiency midium current, AC input high current high efficiency, high current short pulsed, etc. The table below shows a list of our laser drivers/controllers.
