摘要： A nonlinear optical system may include optics, a non-linear optical crystal, and a uni-axial focusing element. The non-linear optical crystal is configured to generate an output beam from a non-linear optical interaction with an input beam. The optics are configured to image the input beam to an original input beam waist within the non-linear optical crystal, whereby the output beam has an original output beam waist. The uni-axial focusing element is optically coupled to the non-linear optical crystal. The uni-axial focusing element is configured so that the output beam has a new output beam waist at approximately the same location as the original output beam waist.

摘要： An optical fiber connector apparatus may include a ferrule having a hollow through its center. The hollow is sized and shaped to receive an optical fiber such that an end of each of the optical fiber is located at an endface of the ferrule. The endface of the ferrule is partitioned into a first section and a second section. The first section is perpendicular to an axis of the ferrule and the second section is angled with respect to the first section. When the connector is assembled, the ferrule can butt couple to a similarly configured second ferrule such that the perpendicular second portions of the endfaces of the ferrules are physically touching. The angle of the angled portions sets a distance between portions of the endfaces corresponding to endfaces of optical fibers received in the ferrules thereby setting a gap between the fiber endfaces.

摘要： Control of average wavelength-converted power and/or wavelength converted pulse energy is described. One or more seed pulses may be generated and amplified with an optical amplifier to produce one or more amplified pulses. The amplified pulses may be wavelength converted to produce one or more wavelength converted pulses characterized by an average wavelength-converted power or pulse energy. Wavelength-converted power or pulse energy may be controlled by adjusting wavelength conversion efficiency without substantially changing the amplified power or pulse energy. Average wavelength-converted power may be controlled over a time scale comparable to a pulse period of the amplified pulses without adjusting an average power of the amplified pulses over the time scale comparable to a pulse period of the amplified pulses. A wavelength-converted optical system, may comprise a seed source, an optical amplifier optically coupled to the seed source, a wavelength converter optically coupled to the optical amplifier; and a controller operably coupled to the seed source and/or optical amplifier and/or wavelength converter. The controller may include logic adapted to control an average wavelength-converted power of an output of the wavelength converter over a time scale comparable to a pulse period of amplified pulses from the optical amplifier without adjusting an average power of the amplified pulses over that time scale. Alternatively, the controller logic may be adapted to control wavelength-converted pulse energy by adjusting the wavelength conversion efficiency without substantially changing the pulse energy of the amplified pulses.

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： Laser apparatus and methods involving multiple amplified outputs are disclosed. A laser apparatus may include a master oscillator, a beam splitter coupled to the master oscillator, and two or more output heads optically coupled to the beam splitter. The beam splitter divides a signal from the master oscillator into two or more sub-signals. Each output head receives one of the two or more sub-signals. Each output head includes coupling optics optically coupled to the beam splitter. An optical power amplifier is optically coupled between the beam splitter and the coupling optics. Optical outputs from the two or more output heads do not spatially overlap at a target. The master oscillator signal may be pulsed so that optical outputs of the output heads are pulsed and substantially synchronous with each other.
