    摘要： In a pulsed Fabry-Perot laser, such as a Q-switched laser or a mode-locked laser, one of the resonator reflectors comprises a waveguide loop coupled to the gain medium via a circulator. In one embodiment, only a modulator is located in the loop. In another embodiment, the circulator is switchable and the loop may contain either an unidirectional device, such as an isolator, or may contain only the waveguide itself, depending on which states of the circulator are utilized in the switching process. Also described are several arrangements for multiplexing lasers of different operating wavelengths.

    摘要： An elongated laser element is provided with a light energy reflective termination at one end and its opposite end is optically ground and polished normal to the axis of the element to provide a Fresnel-reflective termination at such other end. The laser is adapted to emit stimulated emissive radiation exiting as a beam through its Fresnel-reflective end, and a laser-light transmissive member is supported axially of the element in the path of the emitted beam of light energy. This member has at least one pair of at least partially reflective surfaces which receive laser-light energy from the laser element and reflectively return laser-light energy The path or paths traversed through this member by laser light reflected by one or more reflective surfaces of the member has or have a length equal to an odd integral number of quarter wavelengths at the wavelength of at least one preselected laser-light energy returned by the transmissive member to the laser element substantially augments the stimulated emission by the element of laser-light energy at the wavelength of each such preselected frequency component.

    摘要： In a pulsed Fabry-Perot laser, such as a Q-switched laser or a mode-locked laser, one of the resonator reflectors comprises a waveguide loop coupled to the gain medium via a polarization splitter/combiner. In one embodiment, only a switchable isolator is located in the loop, thereby significantly reducing insertion loss.

    摘要： A length of an optical fiber having a core and a surrounding cladding is held by a block with a portion of said length having substantially all of its cladding removed on one side of the portion and being exposed, and an index overlay perturbation pad is mounted near and substantially parallel to the portion. A translator moves the pad between a first position in which the pad is sufficiently remote from the portion to allow total internal reflection in the portion and a second position in which the pad is sufficiently close to the portion to allow light to escape from the core. The pad may be made of a metal for polarized modulation, or of a dielectric for unpolarized modulation. The optical switch provides very fast switching for a O-switched fiber laser.

    摘要： A Q-switched laser having a gain medium disposed within a first cavity and a second cavity whose optical path length is adjustable such that the quality of the first resonant cavity is affected. One aspect of the invention is the changing of the physical path length of the second cavity so as to affect the reflectivity of a mirror common to both cavities as seen from the first cavity. Another aspect of the invention is the incorporation, within the second cavity, of a material whose refractive index or absorption coefficient can be varied by the application of an electric field, a magnetic field, a temperature change or an applied pressure.
