一、前言高重复率的 Q 开关钕:钇铝柘榴石激光器的广泛使用需要一种能测量几瓦的平均功率,并且能经受住10ns 脉冲的能量密度超过1Jcm~(-2)的激光功率计。解决能量密度产生损害的通常办法是使用热粘接到金属底座上的体积
I. INTRODUCTION High repetition rate Q-switched neodymium: The widespread use of yttrium aluminum garnet lasers requires a laser power meter capable of measuring an average power of a few watts and capable of withstanding a 10 ns pulse with an energy density of more than 1 Jcm -2 . A common solution to the detriment of energy density is to use a volume that is thermally bonded to the metal base
