S-2 QCL Pulser
The S-2m QCL Pulser is designed to provide fast, high impedance current pulses to non-linear current driven devices such as quantum cascade lasers. The generated pulses have a rise time between 5 and 15 ns.
The S-2m pulser is controlled directly through a computer terminal when the S-2m is connected by a serial or USB cable. You will need a driver to operate the pulser, the driver can be dowloaded here: S-2m Driver Software.
If you purchased a driver prior to July 2022 an older version of the software may be needed, please write to us with the serial number of your driver for more information.
If your computer does not recognize the USB-RS 232 converter, you can find a driver here; most computers should recognize the converter without a specific installation.
If you wish to control the driver through direct Python commands, you can find more information in §5.2 of the S-2m User Manual.
