摘要： A method of intracavity frequency conversion in a CW laser includes causing fundamental radiation to circulate in a laser resonator. The fundamental radiation makes a first pass through an optically nonlinear crystal where a fraction of the fundamental radiation generates second-harmonic radiation in a forward pass through the crystal. The residual fundamental radiation and the second-harmonic radiation are then sum-frequency mixed in forward and reverse passes through an optically nonlinear crystal such that a fraction of each is converted to third-harmonic radiation. The residual second-harmonic radiation and fundamental radiation from the sum-frequency mixing then make a reverse pass through the second-harmonic generating crystal where the second-harmonic radiation is converted back to fundamental radiation. The third harmonic radiation can be delivered from the resonator as output radiation, or can be used to pump another optically nonlinear crystal in an optical parametric oscillator. Second-harmonic radiation can also be used to pump an optical parametric oscillator.

摘要： A projection video display includes at least one laser for delivering a light beam. The display includes a beam homogenizer and a condenser lens. A scanning arrangement is provided for scanning the light in beam in a particular pattern over the condenser lens in a manner that effectively increases the beam divergence. The scanned beam is homogenized by a beam homogenizer and a spatial light modulator is arranged to receive the homogenized scanned light beam and spatially modulate the beam in accordance with a component of an image to be displayed. Projection optics are projecting the homogenized scanned light beam onto a screen. The scanning provides that the homogenized scanned light beam at the screen has a coherence radius less than the original coherence radius of the beam. The reduced coherence radius contributes to minimizing speckle contrast in the image displayed on the screen. The screen includes one or more features providing a further contribution to minimizing speckle contrast in the displayed image. In one example, the screen includes a transparent cell containing a liquid having light scattering particles in suspension.

摘要： A semiconductor laser includes a multilayer semiconductor laser heterostructure including at least one active layer of a II-VI semiconductor material (26) and is optically pumped by one or more indium gallium nitride (InGaN) diode-lasers (38). Group II elements in the II-VI semiconductor material are zinc, cadmium, magnesium, beryllium, strontium, and barium.

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.

摘要： A CW fiber- laser includes a gain fiber (42) having a reflector (44) proximity-coupled to one end (42A), with the other end left (42B) uncoated. A laser resonator is defined by the reflector (44) and the uncoated end (42B) of the gain-fiber. Pump - radiation from two fast-axis diode-laser bar stacks (46) is combined and focused into the uncoated end (42B) of the gain - fiber for energizing the fiber. Laser radiation (37) resulting from the energizing is delivered from the uncoated end of the gain -fiber and separated from the pump - radiation by a dichroic mirror (31). A coupler (60) is provided at the uncoated end (42B) of the fiber to absorb pump light not guided in the cladding of the fibre (42).

摘要： A master oscillator power-amplifier stages includes multiple stages of fiber-amplification (34, 54, 58) with a final power amplifier stage in the form of a multi-pass amplifier (64). With a thin-disk gain medium (66) in one example the thin-disk amplifier includes a common optical arrangement (74, 76, 78, 120) for providing multiple incidences of radiation to be amplified and multiple incidences of a pump - radiation beam (70) on the thin-disk gain medium (66). The use of a thin-disk power amplifier allows to avoid non-linear pulse broadening, circumvents the need for a CPA while keeping the footprint of the MOPA small.

摘要： A longitudinal diode-laser array includes a plurality of diode-laser emitter groups. The emitter groups are mounted on corresponding electrical contacts electrically isolated from each other on a dielectric carrier. The emitter groups are cut from a conventionally formed diode- laser bar bonded to the carrier. The emitter-groups are connected together in electrical series via the electrically isolated electrical contacts. This provides that the diode-laser array can be operated at a lower current than would be required to operate the conventional diode-laser bar wherein the plurality of emitters must be connected in parallel.
