One of the shortcomings of laser diode based direct detection laser crosslink technology in a direct comparison to EHF crosslinks has been its inability to operate through the solar flux background levels. Previous solutions involved high peak power solid-state laser designs and constellation rerouting...
A high efficiency and high power laser diode (LD) face-pumped quasi-continuous-wave (QCW) ceramic Nd:YAG zigzag slab laser is demonstrated. The shape of the LD pump beam is optimized to ensure that the pump size is well matched with the ceramic slab and to improve the uniformity of the...
Efficient cw and passively Q-switched operation with self-stimulated Raman scattering conversion was demonstrated in a compact diode-pumped Yb:KLu(WO4)2 laser. A cw output power of 3.28 W was obtained with an optical efficiency of 48.2% and a slope efficiency of 78.2% with respect to the in...
Diode array providing either a pulsed or a CW mode 优质文献 相似文献 参考文献 引证文献Active and passive Q-switching of a diode pumped Nd:KGW-laser Efficient operation of a pulsed diode-pumped Nd:KGW laser is reported in actively and passively Q - switched operation. A 6mm long laser rod...
A planar electron-beam diode with a strong magnetic field imposed normal to the electrode surfaces is found to operate as a fast opening switch when the electric field of the cathode is artificially enhanced with an array of needles as the emitting structure. Conduction times of hundreds of nano...
The high-power operation of a diode edge-pumped, composite Yb<SUP>3+</SUP>-doped Y<SUB>3</SUB>Al<SUB>5</SUB>O<SUB>12</SUB> (Yb:YAG) microchip laser has been demonstrated. The novel hybrid composite microchip has a 5-mm-diameter, 300-µm-thickness, single-crystal Yb:YAG core ...
We report an experimental study of the contrast ratio needed for single-ended operation of diode-clamped optical receivers. These receivers, realized in field-effect-transistor-self-electrooptic-effect device (FET-SEED) technology, are high impedance FET-based receivers designed to operate with two ...
High‐power constricted double‐heterojunction AlGaAs diode lasers for optical recording In this letter we describe a new type of constricted double‐heterojunction injection laser especially designed for optical disk recording. The laser is ca......
