Review on Ultrashort Pulse Laser Amplifiers Based on Bulk Yb-Doped Gain Media
摘要
掺镱块状材料是产生高功率超短脉冲激光输出的一种有效技术途径,具有造价低、易加工、易调节、可承受脉冲能量大等优势。该材料介于光纤、单晶光纤、板条、薄片之间,基于块状材料的超短脉冲激光放大器逐渐成为超快激光领域的研究热点。在具体体现形式上,主要有行波(单通、双通、四通)放大结构和再生放大结构;在所使用的增益介质方面,主要以Yb∶YAG为主,另外还有Yb∶KYW、Yb∶KGW、Yb∶CALGO、Yb∶CaF2、Yb∶Lu2O3、Yb∶Y2O3等。梳理和总结了目前已经公开报道的相关结果,并对掺镱块材料超短脉冲激光放大器,尤其在百瓦甚至千瓦量级的超短脉冲放大器上的潜在应用及未来发展趋势进行了探讨和展望。
Abstract
Yb-doped bulk materials are becoming an effective technical way for delivering high power ultrashort pulse lasers. They are inexpensive and easy to be processed, adjusted, and resistant to higher pulse energy, all of which make bulk-material-based ultrashort pulse laser amplifier be a hot topic. Usually, there are two kinds of configuration for amplifiers, travelling-wave (single, double-pass, four-pass) amplifiers and regenerative amplifiers. The gain media are not limited to the well-known Yb∶YAG, Yb∶KGW, and Yb∶KGW, such new candidates as Yb∶CALGO, Yb∶CaF2, Yb∶Lu2O3 and Yb∶Y2O3 are also emerging. Efforts are paid to review currently reported representative results, to show the potential application of Yb-doped bulk materials as the base for generating ultrashort pulse lasers with average power from hundreds of to thousands of watts.
