The acousto-optic method of summing the power of two lasers of the same type with modulation and intensity control is based on the simultaneous diffraction of two laser beams in one acousto-optic paratellurite crystal on one acoustic wave. For lasers with wavelengths from 400 to 1000 nm, the frequency range of acoustic waves is 30–5 MHz. The method is applicable to both continuous and pulsed lasers. Using the example of the addition of the powers of continuous semiconductor lasers (power 10 W and wavelength 532 nm), it is shown that the total power was 19.2 W.

一种激光辐射声光加法器-调制器

通过调制和强度控制对两个相同类型的激光器的功率求和的声光方法是基于两个激光束在一个声光副碲晶晶体中对一个声波的同时衍射。对于波长为 400 至 1000 nm 的激光器，声波的频率范围为 30-5 MHz。该方法适用于连续和脉冲激光器。以连续半导体激光器（功率10 W，波长532 nm）的功率相加为例，总功率为19.2 W。
