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 1):
An infrared laser, comprising:\n a. a quantum cascade laser gain medium having a first end and a second end; b. a first collimating lens adjacent to the first end of the gain medium and receiving a first undiffracted beam from the gain medium defining a first path; c. an anti-reflection coating at the first end of the gain medium, the anti-reflection coating facing the first collimating lens; d. a second collimating lens adjacent to the second end of the gain medium and receiving a second output beam from the gain medium; e. a partially reflective coating at the second end of the gain medium, the partially reflective coating facing the second collimating lens; f. a first acousto-optic modulator adjacent to the first collimating lens and opposite the gain medium and fixed in place, the first acousto-optic modulator having a first radiofrequency and receiving the first undiffracted beam and subsequently emitting a diffracted beam; g. a second acousto-optic modulator through which the diffracted beam passes, the second acousto-optic modulator having a second radiofrequency; and h. a first highly reflective mirror positioned to receive the diffracted beam from the second acousto-optic modulator, and reflect the diffracted beam back to the second acousto-optic modulator to the first acousto-optic modulator and back to the gain medium to amplify a wavelength tuned beam, wherein the first and second acousto-optic modulator radiofrequencies are electronically controlled to produce the diffracted beam at a desired optical wavelength, i. wherein the first acousto-optic modulator comprises:\n (i) a first transparent material having a first end and a second end opposite the first end, a first facet adjacent to the first and second ends, and a second facet opposite the first facet and adjacent to the first and second ends, the first transparent material having anti-reflection coatings on the first and second facets at the desired optical wavelength; and \n (ii) a first piezoelectric transducer at the first end of the first transparent material, the first piezoelectric transducer being controlled by a first radiofrequency generator, and \n j. wherein the second acousto-optic modulator comprises:\n (i) a second transparent material having a first end and a second end opposite the first end, a first facet adjacent to the first and second ends, and a second facet opposite the first facet and adjacent to the first and second ends, the second transparent material having anti-reflection coatings on the first and second facets at the desired optical wavelength; and \n (ii) a second piezoelectric transducer at the first end of the second transparent material, the second piezoelectric transducer being controlled by a second radiofrequency generator, \n (iii) wherein the first acousto-optic modulator is oriented oppositely compared to the second acousto-optic modulator so that the second acousto-optic modulator cancels out a Doppler shift of an optical radiation caused by the first acousto-optic modulator.
