Item Description

An R&D 100 Award Finalist 

Block Engineering's LaserTune is a turnkey, compact-packaged quantum cascade laser system that covers a tunable gap-free mid-infrared range of 5.4 to 12.8 microns. 

The full range is covered by packaging four QCL modules in the system. However, for customers who do not need the maximum wavelength range, the system can be configured with 1, 2, or 3 modules instead. Gap-free tuning is maintained in narrower configurations. 

No external power supply, control peripherals, or external cooling systems are required. The LaserTune can be programmed to operate in several modes, including Move Tune (manual control), Step Tune with programmable steps, and Sweep Tune with programmable sweep parameters. LaserTune offers an extremely fast sweep capability at 25 cm-1 per millisecond. 

The system supports pulse durations of between 30 to 300 nsec, a repetition rate of up to ~3 MHz, and a duty-cycle of up to 8%. The pulses can be internally triggered at regular intervals with an available sync-out signal. External triggering is also supported. The beam size is roughly 2 mm x 4 mm.
