Opto-acoustic power monitor with high sensitivity
A new type of laser power monitor based on opto-aooustio effect is described in this paper. The spectral response rang es from UV to IK. In visible spectral region, the responsibility of the monitor is aboat 26 μV/μW, the minimum detectable power is 0.2μV/μW, and the linear dynamic range is over 104.
