瑞士联邦技术研究所和瑞士d’Electronique et de Microtechnique—Zurich中心的研究人员与Time—Bandwidth产品公司的研究人员合作研制了一种Nd:YAG二极管泵浦的被动锁模激光器.该激光器具有10.7W的平均功率和7.8kW的峰值功率.单路通过KTP晶体的外倍频在532nm时能产生3.2W的平均功率,继之通过BBO的倍频产生120mW的紫外输出.激光腔的设计应适合于更高的功率,它由四反射镜组成(包括一块半导体饱和吸收反射镜,一块布鲁斯特板,一个用两个20W二极管棒直接耦合泵浦的激光头).两个曲面镜控制激光头中和半导体饱和吸收反射镜上的激光模半
Researchers at the Swiss Federal Institute of Technology and the Swiss Center d’Electronique et de Microtechnique-Zurich partnered with researchers at Time-Bandwidth Products Inc. to develop a passive mode-locked Nd: YAG diode-pumped laser with a 10.7W Of the average power and 7.8kW peak power. Single through the KTP crystal external multiplier at 532nm can produce average power of 3.2W, followed by BBO multiplier to produce 120mW UV output. Laser cavity design should be suitable for Higher power, which consists of four mirrors (including a semiconductor saturable absorption mirror, a Brewster plate, and a laser head that is directly coupled with two 20W diode rods.) Two curved mirrors control the laser head to neutralize Semiconductor saturation absorber mirror half laser mode
