摘要： An intracavity resonant Fabry-Perot saturable absorber (R-FPSA) induces modelocking in a laser such as a fiber laser. An optical limiter such as a two photon absorber (TPA) can be used in conjunction with the R-FPSA, so that Q-switching is inhibited, resulting in laser output that is cw modelocked. By using both an R-FPSA and a TPA, the Q-switched modelocked behavior of a fiber laser is observed to evolve into cw modelocking.

摘要： A laser tuning mechanism which embodies “spectrally dependent spatial filtering” (SDSF) and contemplates two key elements of the tuning mechanism. The first element of the SDSF tuning mechanism is a spectrally dependent beam distortion (i.e. alteration of the amplitude and/or phase profile of the beam) provided by an SDSF tuning element in a laser cavity. The second element of the SDSF tuning mechanism is an intracavity spatial filter which makes the round trip cavity loss a sensitive function of both beam distortion and cavity alignment. Such a laser can be aligned so that a specific beam distortion, which is provided by the SDSF tuning element at a tunable wavelength, is required to obtain minimum round trip cavity loss, thereby providing tunable laser emission. A preferred embodiment of the SDSF tuning mechanism is an external cavity semiconductor laser having a zeroth order acousto-optic tuning element.
摘要翻译：激光调谐机制体现了“光谱依赖空间滤波”（SDSF），并考虑了调谐机制的两个关键要素。 SDSF调谐机构的第一要素是由激光腔中的SDSF调谐元件提供的频谱依赖的光束失真（即光束的振幅和/或相位分布的改变）。 SDSF调谐机构的第二个元素是腔内空间滤波器，其使得往返腔体损耗具有波束失真和腔体对准的敏感功能。这样的激光器可以对齐，使得由SDSF调谐元件提供的可调谐波长的特定光束失真是需要的，以获得最小的往返腔损耗，从而提供可调谐的激光发射。 SDSF调谐机构的优选实施例是具有零级声光调谐元件的外腔半导体激光器。

摘要： Lasers are provided to deliver a wide variety of wavelengths at variable pulse energy. A laser cavity is formed between a first and second reflective surface. A lasing medium is located within cavity which lases at a preselected fundamental frequency. One or more nonlinear crystals are provided in optical communication with the lasing crystal to produce a secondary beam having a different frequency than the fundamental beam. A modulator is provided to control the pulse energy of the secondary beam. Desirably the secondary beam is a harmonic beam for example a second, third, fourth or fifth harmonic beam or a beam provided by an optical parametric oscillator.

摘要： A laser to produce pulses of light having predetermined spectral shapes, comprising a waveguide, an optical pump source, a gain medium to produce seed radiation, and a modulator and an array of Bragg gratings to modify the properties of the seed radiation. Once generated by the gain medium, the seed radiation propagates in the waveguide where it is first pulsed by the modulator. The resulting pulses are then selectively reflected by the Bragg gratings, which separates different spectral components of the reflected beam. This reflected beam then travels back to the modulator, which is timed to let only the desired spectral components go through. In this manner the laser is self-seeded and allows spectrum and wavelength selection from pulse to pulse.

摘要： A laser-diode-pumped solid state laser in which a solid state laser crystal is pumped by a light beam produced by a laser diode and which is not lower than 10 W in the internal power of the resonator includes a temperature control circuit which keeps the inside temperature of a resonator at a predetermined temperature and, a wavelength selector which is disposed in the resonator and selects one of a plurality of oscillation modes in the resonator, thereby making the laser oscillate in a single mode. The wavelength selector has characteristics such that the increase in temperature of the wavelength selector due to absorption of a laser beam is smaller than a value such that when the temperature of the wavelength selector changes by the value or more, the oscillation mode selected by the wavelength selector changes.

摘要： The present invention describes the use of a pair of acoustooptic devices in a laser or other optical resonator to produce a wavelength-dependent deflection of the light without incurring a net frequency shift. This permits rapid electronic tuning of the resonator wavelength, as well as rapid electronic variation of cavity loss, out-coupling fraction, and round-trip phase shift. The dispersive quality of acoustooptic devices in transmission is utilized as a reflection grating substitute. Two mirrors, one an output coupler, a gain medium and two acoustooptic devices arranged for maximum efficiency such that the incident and diffracted beams are approximately at the Bragg angle for each acoustooptic device permit the laser wavelength to be determined by the acoustic frequency.
