摘要： Laser apparatus is disclosed in which fundamental-wavelength optical pulses delivered from a mode-locked laser resonator at a pulse-repetition frequency (PRF) are converted to harmonic-wavelength pulses in an optical delay loop. One example is disclosed in which the harmonic-wavelength pulses are delivered directly from the delay loop. Another example is disclosed in which the harmonic-wavelength pulses are divided by the delay loop into a number of temporally spaced-apart replicas thereof, and the delay loop delivers bursts of replicas of different one of the harmonic wavelength pulses at a burst-repetition frequency equal to or a multiple of the PRF of the resonator.

摘要： A projection video display includes a light source including an OPS-laser delivering laser radiation in multiple transverse modes (a multiple-transverse-mode OPS-laser). The display includes a spatial light modulator for spatially modulating the radiation from the multiple-transverse-mode OPS-laser in accordance with a portion of an image to be displayed. Projection optics project the spatially modulated light on a screen on which the image is to be displayed. In one example the OPS-laser is a diode-laser array pumped OPS-laser and is one of three lasers, one delivering red light, one delivering blue light, and the other delivering green light. The lasers are time modulated such that the spatial light modulator receives light from each of the lasers separately. The OPS laser is directly time modulated by periodically turning the diode-laser array on and off.

摘要： Laser apparatus including two different, pulsed MOPAs, one having a fundamental wavelength of 1064 nm and the other having a fundamental wavelength of 1564 nm, provide trains of optical pulses. The 1064-nm pulses are frequency tripled to 355 nm and the 1564-nm pulses are frequency doubled to 782 nm. The 355-nm and 782-nm pulses are mixed to provide 244-nm pulses. The 244-nm pulses are mixed with residual 1064-nm pulses to provide 198-nm output pulses of the apparatus. The output pulses can be either digitally modulated or amplitude modulated by controlling the phase relationship between the 1064-nm and 1564-nm pulses.

摘要： A laser for delivering laser radiation at a selected one of a plurality of equally-spaced frequencies extending over a frequency range includes a laser resonator defined by two end mirrors. The resonator includes a surface-emitting semiconductor multilayer gain-structure in optical contact with one of the mirrors. A third mirror located in the laser resonator forms an etalon with that mirror. The third mirror is movable for adjusting a peak transmission frequency of the etalon to align with the selected frequency. The resonator end mirrors are spaced apart by an optical distance selected such that the frequency and frequency-spacing of possible longitudinal lasing modes of the resonator correspond with the plurality of equally-spaced frequencies. When the peak transmission frequency of the etalon is aligned with the selected frequency the laser resonator delivers radiation in a single longitudinal mode at the selected frequency.

摘要： A continuously-pumped, repetitively-pulsed, Q-switched laser resonator includes two different gain-media which lase at about the same wavelength. By separately and variably pumping the different gain-media, the laser resonator can efficiently generate output radiation having parameters which stay constant over a much wider range of pulse-repetition frequency than would be possible were either one of the gain-media solely deployed in the resonator. In one embodiment, the laser resonator includes an arrangement for providing near real-time compensation for variations in thermal-lensing in the gain-media resulting from variations in pump-power or pulse-repetition frequency.
