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 16):
A laser, comprising:\n a) a quantum cascade laser gain medium having a first end and a second end; b) a collimating lens adjacent to the first end of the gain medium and receiving an undiffracted output beam from the gain medium, the undiffracted beam defining a first path; c) an anti-reflection coating at the first end of the gain medium; d) an acousto-optic modulator adjacent to the first collimating lens and opposite the gain medium and fixed in place, the acousto-optic modulator receiving the undiffracted output beam directly from the first collimating lens and subsequently emitting a diffracted beam along a second path; e) a reflective mirror positioned to receive the diffracted beam and reflect the diffracted beam back along the second path to the first acousto-optic modulator through the first path and back to the gain medium to amplify a wavelength tuned beam; and f) a radiofrequency generator operatively connected to the acousto-optic modulator, the radiofrequency generator configured to generate two radiofrequencies simultaneously.
