Low Duty Cycle Pulsed QCL System


Model 1101-XX-LP-YYYY-EXT quantum cascade laser system is a low duty cycle pulsed QCL system designed for bench top use. Pulse shaping and power conditioning electronics are enclosed inside along with the hermetically sealed package that includes optics for collimating the output laser beam. The system requires no adjustments in the field and is designed to be stable over long periods of time when operating in a stable temperature environment. Model 1101-XX-LP-YYYY-EXT pulsed QCL system provides a fixed laser pulse width and a fixed pulse repetition frequency with internal trigger or a variable pulse repetition rate triggered by user supplied TTL-level trigger pulses. The pulse width and the internally triggered pulse repetition rate are preset at the factory at user specified values. Additionally, an optional switch selectable four different pulse widths between 50 and 200 nsec can be provided. In both the internally triggered as well as the externally triggered mode, a synch pulse is available for synchronizing user electronics.
