Medium-power CW Raman fiber lasers 总被引:4,自引:0,他引:4
Dianov E.M. Prokhorov A.M. 《IEEE journal of selected topics in quantum electronics》2000,6(6):1022-1028
A review of recent results on medium-power CW Raman fiber lasers pumped by laser diodes is presented. Most attention is given to Raman lasers based on phosphosilicate fibers, the latter providing a number of advantages compared to commonly used germanosilicate fibers 相似文献

A 1-kW CW thin disc laser 总被引:11,自引:0,他引:11
Stewen C. Contag K. Larionov M. Giesen A. Hugel H. 《IEEE journal of selected topics in quantum electronics》2000,6(4):650-657
The thin disc laser is presented as an optimal laser design for the operation of a quasi-three-level laser active medium in the high power regime with high optical efficiency. Numerical calculations of the laser output power show that operation with an output power up to 1 kW with an optical efficiency of 50% and more is possible at room temperature utilizing 16 absorption passes. Scaling of the output power can be realized by scaling the pumped area using one or more discs. The experimental investigations yield a maximum output power of 647 W at 51% optical efficiency for one crystal and of 1070 W with 48% optical efficiency for four crystals at a temperature of the cooling water of 15/spl deg/C. 相似文献

We present a novel design for an efficient, high power (>100 W), continuous-wave (CW) Nd:YAG laser with diffraction-limited performance. It uses side-pumped, sidecooled, zigzag slab which is incorporated in a stable-unstable resonator that has a variable reflectivity output coupler. A geometric magnification of at least 1.3 in the unstable direction can be achieved. Modeled performance characteristics are presented 相似文献

The problem of ranging multiple vehicles traveling at similar speeds using multiple-frequency continuous-wave (CW) radar is considered. A new method based on the compensation of vehicle movement and MUSIC-based time delay estimator is presented. The method is tested using a commercially available multiple-frequency CW radar sensor in real traffic situations. Test results show that the proposed method makes it possible to estimate the positions of two vehicles moving at similar speeds. Test results also demonstrate that under a given bandwidth, the multiple-frequency CW radar can provide about ten times higher resolution as compared with the coherent spread spectrum radar 相似文献
