    • Abstract
  • In order to measure energy of the third harmonic (TH) of a large aperture high power laser experiment platform, with a concave mirror sampling the beam, with a novel absorbing glass element filtering the beam, the influence of the absorbing glass element on the measurement result was experimentally tested. According to the data analysis, by using such a novel absorbing glass element, pure TH laser can be obtained and the influence of the residual fundamental and the second harmonic light is about 0.4%. The uncertainty of energy measurement of the entire TH laser energy can be controlled within 5%, which guarantees the reliability of energy measurement for the laser facility.
