即激光增益媒质，属于一种物质体系，作用是实现粒子数反转，并使光产生受激辐射效应。在激光器中，产生作用的物质是半导体<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>，对其的要求是产生并尽可能地维持粒子数反转状态，在激光的整个发射的进程中，这样的状态应持续。</div><div><br></div><div> 泵浦源</div><div><br></div><div> 属于一种结构或者一种装置，激光工作物质需要实现并维持粒子数反转状态，泵浦源为该过程提供能量。在实际操作过程中，根据不同的初始条件，激励方式可以采用电泵、光泵或者高能<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电子</a>束的形式。</div><div><br></div><div> 光学谐振腔</div><div><br></div><div> 若想产生激光，除了满足上文所述条件之外，还需对光的频率和方向进行筛选，使得光在腔内持续保持放大状态，具有该作用的装置称为光学谐振腔。结构最简单的谐振腔，其两端各有一个镜片，作用为反射，并被称为法布里-珀罗谐振腔。</div><div><br></div><div> 其作用为：(1)使光子在腔内往复振荡；(2)对光的方向和频率加以约束，使最终发射的激光保证具有同一个方向。反射光经多次往返，从而不断放大，最终使光的增益大大提高。同时，谐振腔并非完全使光发散，并且两端的镜片也并非都是全反射，因此光在传播的过程中具有损耗。若增益的量值与损耗达到的值实现相等的状态，激光便会激射。</div><div><br></div><div><section
