S-2 QCL Pulser

S-2 QCL PulserThe S-2 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-2 pulser is controlled directly through a computer terminal when the S-2 is connected by a serial or USB cable. You will need a driver to operate the pulser. If you have a pulser model Rev. 5 (the revision number should be visible on the board) you can use one of these drivers for Mac OS XWindows or for Linux  computers. Older pulsers bought in 2017 or prior may use the older version of the driver which is also available for WindowsMac OS X or Linux.

If the software requires to upgrade the firmware, you can use the firmware upgrader for Mac OS XWindows or for Linux to upgrade to the latest version. 

 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 commands, you can find the API here. You can use the API with no additional fee; optional Service and Support agreements are available.
