Abstract
A highly portable, high-powered infrared laser source is produced by intermittent operation of a quantum cascade laser power regulated to a predetermined operating range that permits passive cooling. The regulation process may boost battery voltage allowing the use of a more compact, low-voltage batteries.
Claims12
A laser assembly comprising:
- a housing;
- a quantum cascade element coupled to the housing;
- and
- a driver circuit that directs a set of controlled pulses of power to the quantum cascade element;
- wherein the driver circuit dynamically adjusts a duty cycle of the pulses of power based on feedback relating to the quantum cascade element.
