Diode driver is designed for supplying the laser diodes and diode bars by pulsed current up to 200A or DC current up to 70A. Produced as an OEM module. The driver allows to change the parameters in wide range.
Laser diode driver / laser diode controller is a current source that delivers exactly the current to the laser diode that it needs to operate for a particular application. It is very important for laser diode module to provide current signal without any overshooting. Our laser drivers are highly stable precise solution with integrated over current protection. It allows us to drive your laser diode absolutely safety. Now we have two main product lines:
STSF6XXX series includes highly current laser driver STSF6250 with output current up to 250A for laser diode bar and high current fiber-coupled module and high voltage laser driver STSF6100 with output voltage up to 40V which perfectly allows to operate with multiple singe emitters fiber coupled laser diodes.
Drivers STSF8XXX include highly stabile current source (0.01А) for laser diode and TEC temperature controller for precision maintaining the temperature on peiltier element (TEM) (0.01°C). Also drivers have large heat sink for stable heat dissipation.
STSF6XXX is the series of high power, compact OEM constant current laser diode drivers. Unique laser driver circuit solutions allows to achieve high efficiency (up to 97%) and high power density. Aluminum base plate provides effective remove heat from laser diode driver module with the water or air cooling. Laser current driver have generous amount of protection features for laser diode safety operating. The main fields of application for high power laser drivers STSF6XXX is laser marking, welding, soldering, and cutting applications, medical equipment, laser measurement equipment, spectrometers, lidar, range finders and laboratory test set-ups.

STSF8xxx series drivers series have special design for supply laser diode in butterfly package with 14 pin pump laser diodes. Driver include high stability current source (0.01mА) for laser diode and TEC for precision maintaining the temperature on peiltier element (TEM) (0.01 °C). Driver have an integrated mounting Azimuth socket for butterfly packaged devices and large heat sink for stable heat dissipation. The main fields of application is laser pumping, laser spectroscopy, laboratory test set-ups.
STSF8xxx contains a laser diode driver and a temperature controller (TEC). Laser diode driver is a non isolated low drop out (LDO) regulator with constant current output. Driver produces high stability and low ripple current. TEC is a non isolated DC/DC. TEC produces low current ripples. Additional features include an adjustable TEC output current limit and Integrated self-adjusted PID controller, providing optimal temperature regulation.
STSF8xxx can be controlled by analogue or digital signals and switches on the board. It is housed in 61×101.6 mm package with aluminum base plate to aid thermal dissipation from laser diode. The laser diode mount is located on the board. Driver can be mounted on any thermal conductive surface enough to dissipate laser diode losses.
