摘要： A laser includes a resonator terminated by first and second mirrors and including a gain medium providing fundamental radiation. A first optically-nonlinear element is located in the resonator. The first optically-nonlinear element is cooperatively arranged with the first mirror to provide passive modelocking of the fundamental radiation by sequentially converting a first portion of the circulating fundamental radiation to second-harmonic radiation and reconverting a first portion of the second-harmonic radiation to fundamental radiation. A second optically-nonlinear element is arranged to convert a second portion of the second-harmonic radiation to either third-harmonic radiation or fourth-harmonic radiation.

摘要： A semiconductor laser includes a multilayer semiconductor laser heterostructure including at least one active layer of a II-VI semiconductor material and is optically pumped by one or more indium gallium nitride (InGaN) diode-lasers. Group II elements in the II-VI semiconductor material are zinc, cadmium, magnesium, beryllium, strontium, and barium. Group VI elements in the II-VI semiconductor material are Sulfur, Selenium, and Tellurium. In one example of the laser an edge emitting heterostructure includes two active layers of zinc cadmium selenide, two waveguide layers of zinc magnesium sulfoselenide, and two cladding layers, also of zinc magnesium sulfoselenide. Proportions of elements in the cladding layer material and the waveguide layer material are selected such that the waveguide layer material has a higher bandgap than the material of the waveguide layers. In another example, a two dimensional array of InGaN diode-lasers is arranged to optically pump a one dimensional array of II-VI edge-emitting heterostructure lasers.

One example is disclosed in which the harmonic-wavelength pulses are delivered directly from the delay loop. Another example is disclosed in which the harmonic-wavelength pulses are divided by the delay loop into a number of temporally spaced-apart replicas thereof, and the delay loop delivers bursts of replicas of different one of the harmonic wavelength pulses at a burst-repetition frequency equal to or a multiple of the PRF of the resonator.

摘要： An optically pumped semiconductor laser includes an active ring-resonator having two or more optically pumped semiconductor (OPS) structures each including a mirror-structure and a multilayer gain-structure. The mirror-structures serve as fold mirrors for the resonator axis. An optically nonlinear crystal may be included in the ring-resonator for generating second-harmonic radiation from fundamental radiation generated in the resonator. Another optically nonlinear crystal may be provided for generating third-harmonic or fourth-harmonic radiation from the second-harmonic radiation. In one example, including a third-harmonic generating crystal, a passive ring-resonator partially coaxial with the active ring-resonator is provided for circulating second-harmonic radiation to provide resonant amplification of the second-harmonic radiation for enhancing third-harmonic conversion. Apparatus for automatically maintaining the passive ring-resonator in a resonant condition for the second-harmonic radiation is disclosed.

摘要： A laser includes a traveling-wave ring-resonator in which one resonator mirror is a mirror of an interferometer arranged such that, when the interferometer is operated in an anti-resonant condition, the mirror has a greater effective reflectivity for clockwise circulation of light in the resonator than for anticlockwise circulation of light in the resonator. There is a difference between the clockwise and anticlockwise effective-reflectivity sufficient that lasing in the resonator is possible only in the clockwise direction.
