摘要： A fiber block is configured with a fiber block including a Nd-doped active fiber and a pump-light delivery fiber which has a stretch extending along the active fiber in a side-to-side configuration so as to lunch pump light into the Nd-doped core of the active fiber. The core of the active fiber is surrounded by at least one or more claddings which, like the core, have a double bottleneck cross-section with a relatively large-area central region and relatively small input and output regions. The pump light delivery fiber is structured to have a substantially dumbbell cross-section with a relatively small-area central region coextending with the central region of the active fibers. The active fiber is dimensioned so that the overall length of the active fiber is configured to provide for the maximal amplification of the laser signal in a 900 nm range while limiting amplification in the 1060 nm range to the preset threshold. The fiber block is further configured so as to have the major fraction of the unabsorbed light, supported in the relatively large-area output end region of the passive fiber, be further used for pumping a neighboring fiber block.

摘要： A resonator assembly (10) particularly suited for a diode pumped solid state laser includes a glass planar support plate (20). At least two transparent mirror mounts (26,28) are bonded to the plate (20) using a UV curable adhesive. The resonator mirrors (22,24) are in turn bonded to the mounts (24,28) using a similar adhesive. The structure is easy to align and assemble and is low in cost. In addition, the assembly can be formed from materials having a low coefficient of thermal expansion so that the thermal stability is enhanced. Further, the transparent mirror mounts (26,28) provide enhanced stability while allowing transmission of laser radiation. A block (40) of a gain medium such as Nd:YAG, may be mounted in a Faraday effect magnet (48) bonded to the plate (20) and the frequency change of the gain medium with temperature be such that the variation of the resonant frequency of the resonator (20,24,40) with temperature maintains stability of operation. A pump beam (74) from a pump diode (70) can be directed through a mirror mount (26) into the resonator (22,24,40).
