CO2激光调Q技术
Q-switch techniques of CO2 laser
摘要
调Q技术是实现小型CO2激光器短脉冲输出的重要手段,近年来随着短脉冲CO2激光器在激光测距、测速、成像雷达、环境探测、空间通讯及激光与物质相互作用等领域应用需求的不断增长,激光调Q技术越来越受到国内外专家的关注而成为红外激光技术的研究热点之一。本文就目前用于CO2激光器中实现短脉冲输出的5种主要调Q技术(机械调Q技术、电光调Q技术、声光调Q技术、被动调Q技术、复合调Q技术)的国内外发展历程和现状进行了综合评述,总结分析了各种方法的关键技术和存在的问题,并简要分析了该技术的未来发展趋势。
Abstract
Short-pulse CO2 laser has significant applications in many fields such as laser ranging, environmental detection, space communication and laser interaction with matter. Q-switch techniques are important approach for generating short-pulse CO2 laser and have been extensively studied by researchers. Main Q-switch techniques for CO2 laser are reviewed in this paper, including mechanical Q-switch, electro-optically Q-switch, acousto-optically Q-switch, passively Q-switch and double Q-switch. The key technical points and problems of each Q-switch technique are summarized and analyzed. In addition, the tendencies of Q-switch techniques for CO2 laser are proposed.
