摘要： An optical amplifier (20, 100) includes an elongated slab (22, 102) of solid state lasing material, such as a rare earth doped yttrium-aluminum-garnet (YAG) slab. In order to provide a relatively increased absorption length and thus a higher overall efficiency, the optical amplifier (20, 100) in accordance with the present invention incorporates end pumping in which the pumped light is coaligned with the amplified light resulting in relatively longer absorption lengths and higher overall efficiencies. The coaligned pumped sources are directed to lateral faces of the slab (22, 102) which include footprints (41, 43, 108) or windows. In order to cause internal reflection of the pump beam along the lasing axis, the end faces (28, 30, 110) are formed at about a 45° angle relative to the longitudinal axis which causes the pumped light to be reflected within the slab co-axially with amplified light. In order to confine the absorption of the pumped light to the center portion of the slab (22, 102), the slab (22, 102) may be formed from a composite material with the opposing end portions of the slab formed from an undoped host material while the center portion of the slab along the longitudinal axis is formed from a doped host material. Such a configuration provides relatively low residual thermal lensing with virtually no birefringence. In one embodiment, the pumping light from the diode arrays is coupled to the slab (22, 102) by way of lenses (54) or lens ducts (FIG. 1). In an alternate embodiment, the pumping light is coupled to the slab (22. 102) by way of optical fibers (104, 106). In yet another embodiment (FIG. 8), the pumping light and laser beams are interchanged forming a low-loss straight through slab with end pumped architecture.

An amplifier module (100,100a,200a) for the solid state laser suitably includes a disk (12) having two substantially parallel surfaces (22,24) and an optical gain material (26). A number of diode bars (68) are arranged about the perimeter of the disk (12) and configured to provide optical pump radiation to the laser gain material in the disk (12). Each of the plurality of diode bars (68) is spatially aligned with the disk (12) in such a manner as to produce substantially uniform gain across the optical gain material. The fast axes of the diode bars (68) may be aligned to be parallel or orthogonal to the parallel surfaces (22,24) of the disk (12), for example.

摘要： A semiconductor laser-excited solid-state laser device which is constituted by mounting a sub-mount, an LD bar, and a light guiding duct on the LD package main body of a semiconductor laser and inserting the emitting section of the LD bar into the light guiding duct. Then a gold-metallized insulating plate is welded to one side of the LD package main body and the LD bar and gold-metallized part are connected by wire bonding. The light guiding duct is constructed so that the duct can directly transmit exciting light to a laser medium and the periphery of the laser medium can be surrounded by a light condenser. When an electric current is made to flow to a cathode from the LD package main body, the LD bar emits LD exciting light and the laser medium is excited, resulting in laser oscillation. Therefore, a highly reliable and highly efficient LD-excited solid-state laser device which can be assembled easily and can be manufactured at a low cost can be obtained.
