Waveplates and Retarders
True zero-order waveplates or retarders features ultra-thin thicknes to produce precisely the desigened fractional retardation in laser systems. Hangzhou Shalom EO provides free standing true zero order waveplates with quarter or half retardation, with high Laser Induced Damage Threshold (LIDT) greater than 1GW/cm^2. Two types of birefringent materials are optional : Quartz for 532-3000nm wavelength or MgF2 for 3000-7000nnm wavelength. The strengthened design modules cemented with BK7 substrates for easy handling are also available, but the cemented type is not recommended for high energy laser applications.
