【摘要】 采用合适厚度,掺杂合适浓度的铈、铕等稀土元素的石英玻璃管制作的脉冲氙灯和滤光套管,其3500埃以下的紫外辐射基本消除,因而在固体激光器中能替代滤光溶液和黄色玻璃滤光套管,防止工作物质着色.比较了不同滤光材料的滤光特性及其在重复频率钇铝石榴石激光器中的激光效率.在Nd:YAG及钕玻璃激光器中,使用掺杂石英玻璃后,可使激光器效率提高25～100%.更多还原

【Abstract】 In pulsed flashlamps and filter envelopes made of quartz tubes with appropriate thickness and proper concentration of doped rare-earth elements, such as cerium, europium etc, UV radiation below 3500 A is essentially eliminated, thus filter solution and yellow glass filter envelopes in solid state lasers can be replaced and the colouring of laser material prevented.Comparison has been made among filtering characteristics of different filter materials and their efficiencies in repetitive pulse Nd:YAG lasers. Experimental results show that using doped-quartz in Nd:YAG laser and Nd:glass lasers, laser efficiency can be increased by (25-100)%, or even higher.更多还原
