Abstract:The laser attenuation device has always been an important component of the LIDT system,the attenuation adjustment ability of the laser attenuation device directly affects the performance of the testing system.The continuous attenuation device of high energy laser is achieved by combining polarization cube with rotating half wave plate,when the angle of the rotating half wave plate changes from 0°to 45°, the transmissivity of the attenuator changes from 99.9% to 0.3%.This design scheme reduces the volume of the… Show more
