产品简介
BATOP 现已成为用于被动锁模激光器的可饱和吸收体的优秀供应商。可饱和吸收产品集合了各式各样的不同的器件，从可饱和吸收镜(SESAM)，到可饱和输出镜(SOC)和用于透过应用的可饱和吸收体(SA)。迄今为止，可饱和吸收产品已经覆盖了800nm到2.6μm的常用激光波长范围。
原理简介
被动锁模技术由于便于组装， 操作简单等优点， 已被人们广泛的应用于各类激光腔中来产生超短脉冲串。被动锁模器件：可饱和吸收镜（SAM） ，可被安装在宽谱激光腔中进行模式锁定。通过可饱和吸收体的损耗机制，连续激光器中杂乱的多脉冲可以被调制成有规律的超短脉冲串。可饱和吸收体在强光下被漂白，可以使大部分腔内能量通过可饱和吸收体到达反射镜，并再次反射回激光腔中；在弱光下，表现为吸收未饱和的特性，吸收掉所有入射光，有效的把这部分弱光从激光腔中去除掉，表现了调 Q 锁模的抑制作用。而且由于吸收掉了脉冲前沿部分，脉冲宽度在反射过程中会逐渐变窄。
