パワー・エネルギー計測

抄録

Recently, lasers are remarkably in use under various circumstances. The measurement of laser power and energy is the most fundamental one, and to know it quantitatively is very important for laser optimization by alignment, daily check as well as the min-max setting and the feedback system control in laser processing application, which leads to better quality control. So the interest in laser measurement is increasing more and more. In this paper I will pick up power meter and explain the principle, how to use and things to remember.
