摘要： In a master oscillator plus power amplifier (MOPA) system (10), the oscillator is a passively Q-switched laser (12). The laser is triggered into passively Q-switched operation by operating an optical switch (40) to resonantly couple back into the laser amplified stimulated emission generated by the amplifier (30). The oscillator comprises a passive Q-switch (20), for example CnYAG, and a gain element (22), for example Nd:YV04. The oscillator is end-pumped by a pulsed LD (14). The amplifier (30) is end-pumped by a LD (34) in a cw-mode. Seeding of the oscillator with ASE emitted by the amplifier is controlled by the optical switch (40) which may comprise a Pockels-cell (42) between two polarizers (44,46). Control of the pulse repetition rate and the duration of pulse bursts emitted by the MOPA is possible via the control of the ASE seeding the passively Q-switched oscillator.

摘要： In order to maintain a constant laser output pulse power in a RF-energized, sealed-off, diffusion cooled, pulsed, CO2 gas-discharge laser (160), each laser output pulse is generated by train or burst of shorter RF pulses. When the time between laser output pulses (176) becomes short enough that the power in one pulse would be reduced by gas-discharge heating effects of a previous pulse, power in the RF pulse trains (164) is varied by varying the duration or duty cycle of pulses in the bursts, thereby keeping output-pulse power in the laser output pulses constant. RF pulses in any burst can have a different duration for tailoring the temporal shape of a corresponding laser-output pulse.
摘要翻译：为了在射频激励密封的扩散冷却的脉冲CO2气体放电激光器（160）中保持恒定的激光输出脉冲功率，每个激光输出脉冲由更短的RF脉冲的串联或脉冲串产生。当激光输出脉冲（176）之间的时间变得足够短以致通过先前脉冲的气体放电加热效应将一个脉冲中的功率降低时，RF脉冲序列（164）中的功率通过改变持续时间或占空比来改变在脉冲串中的脉冲周期，从而保持激光输出脉冲中的输出脉冲功率恒定。任何脉冲串中的RF脉冲可以具有不同的持续时间，用于调整对应的激光输出脉冲的时间形状。

摘要： Designs and techniques for constructing and operating femtosecond pulse lasers are provided. One example of a laser engine includes an oscillator that generates and outputs a beam of femtosecond seed pulses, a stretcher-compressor that stretches a duration of the seed pulses, and an amplifier that receives the stretched seed pulses, amplifies an amplitude of selected stretched seed pulses to create amplified stretched pulses, and outputs a laser beam of amplified stretched pulses back to the stretcher-compressor that compresses their duration and outputs a laser beam of femtosecond pulses. The amplifier includes a dispersion controller that compensates a dispersion of the amplified stretched pulses, making the repetition rate of the laser adjustable between procedures or according to the speed of scanning. The laser engine can be compact with a total optical path of less than 500 meters, and have a low number of optical elements, e.g. less than 50.

摘要： Output pulses from an optical system having a seed source and an optical amplifier coupled to the seed source may be controlled by controlling a power of a seed signal from the seed source. The seed signal may be varied between a minimum value and a maximum value in a way that the seed signal exhibits one or more pulse bursts. Each pulse burst may contain one or more pulses. During an inter-pulse period between successive pulses within a pulse burst or between successive pulse bursts, the power of the seed signal may be adjusted to an intermediate value that is greater than the minimum value and less than the maximum value. The intermediate value is chosen to control a gain in the optical amplifier such that a pulse or pulse burst that follows the period exhibits a desired behavior.

摘要： A pulsed fiber laser generating light pulses in the picosecond range having an adjustable pulsewidth is provided. The fiber laser includes a figure-of-eight type laser cavity, preferably of polarization-maintaining optical fiber, defining reciprocal and non- reciprocal loops. A gain medium is disposed asymmetrically in the reciprocal loop, at a position therealong favoring coupling of light in the propagation direction of the non- reciprocal loop. A pump source is coupled to the reciprocal loop to inject pump light into the gain medium. The laser cavity is designed so that changing the pump power will directly affect the pulsewidth of the generated light pulses, providing a useful control mechanism of the pulsewidth.

摘要： Two pulsed lasers (14) or sets of lasers propagate beams of pulses (20) having orthogonally related polarization states. A beam combiner (24) combines the orthogonal beams to form a combined beam propagating along a common beam path (16) to intersect an optical modulator (30) that selectively changes the polarization state of selected pulses of either beam to provide a composite beam (18) including similarly polarized pulses from the orthogonal beams. The composite polarized beam has a composite average power and a composite repetition rate that are greater than those provided by either laser. The optical modulator can also selectively control the polarization states of pulses from either laser to pass through or be blocked by a downstream polarizer (32). Additional modulators may facilitate pulse shaping of the pulses. The system is scalable by addition of sets of single lasers or pairs of lasers with beam combiners and modulators.
