摘要： Stabilization of an injection locked optical frequency comb is achieved through polarization spectroscopy of an active laser cavity, eliminating optical PM sidebands inherent in previous stabilization methods. Optical SNR of 35 dB is achieved. A monolithic AlInGaAs quantum well Fabry-Prot laser injection locked to a passively mode-locked monolithic laser is presented here. The FP laser cavity can be used as a true linear interferometric intensity modulator for pulsed light.

摘要： A method and apparatus for suppression of stimulated Brillouin scattering (SBS) includes a master oscillator (MO) that generates a beam; a birefringent element that receives and transmits the beam, wherein the beam is transmitted with a transmission delay between two orthogonal axes; a polarization controller that receives the beam and transmits the beam with a desired polarization; a fiber amplifier that receives the beam, amplifies the beam, and transmits a beam; a compensating birefringent element that receives the beam, approximately removes the transmission delay between the two axes of the beam, and transmits an output beam; and a polarization detector that detects the output beam's polarization and provides feedback to the polarization controller to ensure that the polarization of the output beam is approximately equal to a desired output polarization, so as to reduce SBS.

摘要： A system and method for controlling polarization in a fiber amplifier is disclosed. A polarization dither waveform is applied to a polarization controller so that dithering does not trigger PI-HOMI (Polarization-Induced High Order Mode Instability). The dither waveform may have a period that is much less than the thermal diffusion time across the fiber amplifier core. The dither waveform may also have a slew rate (defined in degrees/second on the Poincaré sphere) that is much slower than the thermal diffusion time across the fiber amplifier core.

摘要： The aim of the invention is to machine a material by application of non-linear radiation. The aim is achieved by modifying the laser radiation emitted by a laser beam source with the aid of a polarization modulator in such a way that laser radiation focused into the material is polarized in a linear fashion, the direction of polarization varying across the cross section of the beam.

摘要： Composite optical beams are formed by placing the outputs of several independently controlled beam lines in a close packed array in an output aperture. Each beam line has at least its phase and polarization under automatic control. Further properties of the beam lines that can optionally be under control include time delay (for pulsed systems), intensity, and nonlinear conversion. The optical inputs to the beam lines are coherent, which can be achieved by splitting the output of a single optical source, or by phase locking two or more distinct optical sources to each other.

摘要： Methods and apparatuses for determining the polarization state and for providing polarization control in optical fiber lasers and amplifiers. One embodiment of the invention is an optical fiber amplifying system including a circulator (260) having a first optical port (260a), a second optical port (260b) that is configured to output radiation received from the first optical port, and a third optical port (260c) that is configured to output radiation received from the second optical port; one or more amplifier stages (216) connected in series, together having an optical input (216a) optically coupled to the second port of the circulator, and an optical output (216b); and a polarization detector (240) having an optical input optically coupled to the third port of the circulator. Thereby the polarization state of the amplified radiation can be determined using radiation backscattered from the amplifying stage.
