Abstract
A laser-beam attenuation-measurement method using the first-order diffraction from an acousto-optic modulator is newly developed. The attenuation is determined from the voltage of the 30 MHz driving signal of the modulator. A value of attenuation of more than 50 dB can be measured at 633 nm.
