Abstract:
A semiconductor laser tuned with an acousto-optic modulator. The acousto-optic modulator may generate standing waves or traveling waves. When traveling waves are used, a second acousto-optic modulator may be used in a reverse orientation to cancel out a chirp created in the first acousto-optic modulator. The acousto-optic modulator may be used with standing-wave laser resonators or ring lasers.

Claim (Index 20):
A method for rapid and continuous broadband tuning of a quantum cascade laser electronically without the use of mechanical motion to select a lasing wavelength, comprising:\n a) generating an undiffracted beam from a quantum cascade laser gain medium having a first end and a second end; b) passing the undiffracted beam through a first collimating lens adjacent to the first end of the gain medium, the undiffracted output beam defining a first path; c) passing the undiffracted beam from the first collimating lens to a first acousto-optic modulator adjacent to the first collimating lens and opposite the gain medium and fixed in place, wherein passing the undiffracted beam through the first acousto-optic modulator generates a diffracted beam along a second path; and d) reflecting the diffracted beam off a first reflective mirror and back along the second path to the first acousto-optic modulator, then through the first path and back to the gain medium to amplify a wavelength tuned beam, wherein the first acousto-optic modulator is electronically controlled to produce the diffracted beam at a desired wavelength.
