  • In the miniature Cr4+:YAG passive Q-switched conductive cooling repetitive(Nd,Ce):YAG lasers,replacement of the 100% reflector of its plane-parallel resonator with a TIR(total internal reflection)prism,gives better thermal stability characteristic and the repetitive frequency reaches 5pps. Single laser pulse output gets to 20~25mJ with pulse width smaller than 15ns.The operation ambient temperature range reaches -40℃~+55℃.

Abstract: In the miniature Cr4+:YAG passive Q-switched conductive cooling repetitive(Nd,Ce):YAG lasers,replacement of the 100% reflector of its plane-parallel resonator with a TIR(total internal reflection)prism,gives better thermal stability characteristic and the repetitive frequency reaches 5pps. Single laser pulse output gets to 20~25mJ with pulse width smaller than 15ns.The operation ambient temperature range reaches -40℃~+55℃.
