    摘要: Techniques, devices and systems that stabilize an RF oscillator by using an optical resonator that is stabilized relative to a master RF oscillator with acceptable frequency stability performance. In the examples described, the optical resonator is stabilized relative to the master RF oscillator by using a frequency stability indicator based on two different optical modes of the optical resonator. The P.F oscillator to be stabilized is then locked to the stabilized optical resonator to achieve the acceptable RF stability in the RF oscillator.

    摘要: Low phase noise radio frequency (RF) sources generated by voltage controlled oscillators (VCOs) are described. Optical modulators driven by a VCO may be used to generate optical side-bands to cw lasers. The spectral extent of said side-bands can be increased via frequency broadening in highly nonlinear waveguides. Free running mode locked low phase noise comb oscillators can be used as reference oscillators to generate beat signals between those side-bands and individual comb modes at distal spectral regions, thereby creating an error signal used to reduce the phase noise of VCOs and the generation of low phase noise RF signals. VCO phase noise may be reduced by using free-running modelocked comb lasers phase locked to external frequency references, by omitting a reference comb and using a nonlinear interferometer for generating an error signal, or by locking a slave comb to the modulation frequency of an intra-cavity modulator driven by the VCO.

    摘要: A hybrid laser source including a solid state laser driven by an array of fiber laser amplifiers, the inputs of which are controllable in phase and polarization, to compensate for distortions that arise in the solid state laser, or to achieve desired output beam properties relating to direction or focus. The output beam is sampled and compared with a reference beam to obtain phase and polarization difference signals across the output beam cross section, at spatial positions corresponding with the positions of the fiber laser amplifiers providing input to the solid state laser. Therefore, phase and polarization properties of the output beam may be independently controlled by predistortion of these properties in the fiber laser amplifier inputs.

    摘要: A laser system includes two separate active laser-resonators. A first of the laser-resonators delivers laser-radiation at a first wavelength, and the second generates fundamental laser-radiation at second wavelength. The second resonator includes an optically-nonlinear crystal. The radiation delivered by the first laser-resonator is mixed in the optically-nonlinear crystal with the fundamental radiation circulating in the second resonator thereby generating radiation having the sum frequency of the first and second wavelengths. In one example, an OPS-laser-resonator having a fundamental wavelength of 976 nm includes a CLBO crystal. 244 nm radiation from an intracavity-frequency-doubled 488 nm argon-ion laser is mixed in the CLBO with the 976 nm radiation to provide 195 nm radiation.
