Abstract

Laser energy adjustment is the important component in the laser Micro-Nano fabrication, life science, photo sensing detection and optical communication, in order to satisfy the demand of the continuous and dynamically laser energy, the laser energy attenuation dynamic range, attenuation accuracy and attenuation rate should be taken into account. A high-precision controllable and continuous laser energy attenuator based on Polarizing Beam Splitter (PBS) prism was presented in this paper, and the laser energy attenuation dynamic range, attenuation accuracy and attenuation rate of the attenuator were analyzed, furthermore, the calibration methods were introduced. The test results show that the laser energy attenuation dynamic range is 0-30dB, and the dynamic attenuation error is less than ±0.2dB at 3 dB/s of attenuation rate, the attenuator satisfies the requirement of high-precision controllable and continuous laser attenuation.
