摘要： According to an embodiment of the disclosure, a Raman generator includes a Raman medium and one or more optical elements. The Raman medium is configured to receive a pump pulse at a first wavelength and shift at least a portion of the pump pulse energy or power into a Stokes-shifted pulse at a second wavelength. The one or more optical elements are configured to pass the pump pulse and the Stokes-shifted pulse multiple times through the Raman medium. Each pass of the pulses through the Raman medium follows a path. Each path is parallel or anti-parallel to the other paths.

摘要： There is provided an output coupler modulated laser. The laser includes an optical resonator for light to circulate within, a gain medium housed within the optical resonator and a pump. An output coupler included in the optical resonator is responsive to a control signal to generate a modulated optical signal at a laser output port, and a complementary signal at a through port to retain circulating light within the optical resonator. The output coupler and the pump are jointly controllable to maintain the power level of the circulating light substantially at a selected, steady state level, and to decouple the modulation response of the laser from the intrinsic response of the circulating light due to interaction with the gain medium. The output coupler is configurable for simple amplitude modulation, Phase-Shift Keying (PSK), Quadrature Amplitude Modulation (QAM), and is suitable for use with high-finesse, micron or millimeter scale resonators.

摘要： An outcoupler having a wavelength selective, angle sensitive element or Bragg grating and an arrangement for maintaining the element in a predetermined orientation relative to an incident beam of electromagnetic energy. The Bragg grating may be reflective or transmissive. The inventive outcoupler may be used to implement a phase conjugate master oscillator power amplifier with an oscillator; a resonator in operational alignment with the oscillator; and an outcoupler in alignment with the oscillator. In the best mode, second and third Bragg gratings are included within the oscillator and the resonator, respectively.

摘要： A system for producing a laser light pulse is disclosed. The system includes a travelling wave or ring laser incorporating a gain medium with polarizing means for introducing substantially polarized radiation having a first polarization state into the travelling wave laser and output coupling means to substantially output couple radiation having an output polarization state from the travelling wave laser. The system further includes polarization changing means incorporated into the optical path of the travelling wave laser for changing the polarization of radiation having the first polarization state to a seeding polarization state, wherein radiation with the seeding polarization state seeds the gain medium, and radiation intensity modulation means for modulating the intensity of radiation in the travelling wave laser to vary the feedback of radiation into the gain medium, wherein the radiation intensity modulation means also modulates the radiation with respect to the output coupling means.
