Multi-layer Dielectric Film for Pulse Compressed Gratings
Diffraction efficiency and laser induced damage threshold relay on the optical character,and the laser induced damage character and mechanical character of multiplayer dielectric gratings(MDG) are used in Chirped-pulse amplification. A multi-layer dielectric stack design used at 1053 nm and exposed at 413 nm is given. The analysis show that H3L(H2L)^9H0.5L2.03H meets the requirement of MDG. At last,the optical character of the sample is tested. There is a good agreement between the test of transmittance curve and the design. Laser induced damage thresholds are 14.14 J/cm2 and 9.32 J/cm2 respectively when laser incident vertically and 51.2°. The multi-layer dielectric used in MDG represents compression stress force.
