This picosecond high-speed semiconductor laser supply is described as the world's fastest seed-source driver, for picosecond lasers, DVD control, and printing. Output0-1.6A meets short-pulse single-mode diode requirements; an input trigger generates pulses from<500ps to 5ns. Current pulse-width input:RS232. Current-setting input:RS232. TEC setting:RS232. Measured 560ps pulse result.

Board Supply Voltage: 5VDC+-5% (Powered Directly from the LD Interface, from the Temperature-Control Board through the6-Pin IDC Interconnect, or by a Separate5V Supply) Board Supply Current: 0.1A PWM Frequency: 0.04-500kHz

The semiconductor-laser driver control board supports one semiconductor-laser (LD) power-driver board made by the company. In addition to setting and displaying current and controlling current output, it supports external analog current control and optional connection of 1 company-made temperature-control board. Combined with an LD driver board and a temperature-control board, it forms a complete semiconductor-laser power-supply system. The display board is easy to integrate and can be mounted directly in a panel as small as 2U. Supported LD driver boards: the company's STXF series. Supported temperature-control boards: the company's STXF series. Ordering information: semiconductor-laser power-driver control board, model STXF-CDM/-P. The -P suffix specifies a black panel; omit the suffix for the version without a panel. Examples: STXF-CDM, STXF-CDM-P. Dimensional drawing. User guide. Connection is simple: directly connect this board to the LD driver board through their 6PIN interfaces, pin to corresponding pin.
