The HY6410 Laser Diode Driver is a high speed, high current solid-state hybrid laser diode driver. It incorporates a patented technique of "backmatching" which allows remote drive of the laser diode through a 50 coaxial transmission line. This technique allows physical and thermal isolation of the laser diode and the driver. The laser diode can be driven through a transmission line without the need for a matched impedance termination. This removes a large source of heat that can be detrimental to high performance laser diode systems.
