Intermittent CW driver
The ICW driver is dedicated to the usage of a QCL laser using the ICW modulation scheme which allows one to perform spectroscopy with slow detectors while using lasers at low duty cycle.
This scheme was developped in collaboration with the Air Pollution / Environmental Technology group of EMPA. More information and details can be found in the paper published here.
