摘要： Disclosed is a pair of channel waveguide CO.sub.2 lasers formed in a commoneramic block. Both discharge channels are DC excited for CW operation and share common mirrors at both ends. The laser cavity includes a Stark cell coupled via a window to one end of both discharge cannels and contains ammonia or deuterated ammonia. The Stark cell is further truncated by a grating opposite the window to provide an overall three mirror cavity configuration which permits predetermined laser line selection. The Stark cell, moreover, is configured to include two pairs of electrodes which permit independent voltage modulation of the two CO.sub.2 laser beams.

摘要： In one application, the apparatus is used with unstable laser resonators which include a gain region defined by a concave mirror and a convex mirror. The apparatus includes a spectral line selection medium, such as a multiple band pass filter or a multiple diffraction grating, which is located so that the laser beam directed out of the laser gain region impinges thereon. A retroreflector is positioned so that the spectral lines selected by the line selection medium are reflected back into the laser gain region along the propagation path of the incident beam, resulting in a lockup of the laser at the selected spectral lines.

摘要： A tunable optical bandpass filter arrangement which, in a preferred embodiment, exhibits an output which is collimated and co-linear (with the input) and has relatively low transmission losses, together with capability for multi-bandpass operation as well as for non-critical tuning and for correction of optical aberrations, this done automatically over an entire wavelength region, to thus constitute an attractive filter for applications such as intra-cavity line section with multi-line, broad band, lasers, especially at higher power, and useful for rapid scan spectroscopy, for selective photolysis or the like.

摘要： A pulse stretching fiber oscillator (or laser cavity) may comprise a chirped fiber Bragg grating (CFBG) and an optical circulator arranged such that a first portion of a beam that is transmitted through the CFBG continues to propagate through the laser cavity while a second portion of the beam that is reflected from the CFBG is stretched and chirped by the CFBG and directed out of the laser cavity by the optical circulator. Accordingly, a configuration of the CFBG and the optical circulator in the laser cavity may enable pulse stretching contemporaneous with outcoupling, which may prevent deleterious nonlinear phase from accumulating prior to stretching.
