Quantum cascade laser suitable for portable applications

摘要

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.

主权项

1. 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.
