Thin AgGaS2 Crystals for DFG → 2.5-1.3µm

AgGaS2 (AGS) infrared crystal is transparent from 0.53 µm to 12 µm. Thin AgGaS2 (AGS) crystal plates are popular for ultrashort pulse generation in mid IR range by difference frequency generation employing NIR wavelength pulses.

 

Thin AGS crystal plates are provided with BBAR coating. It is a multilayer dielectric antireflection coating made at specified wavelength range. Standard coating is designed to reduce reflection losses at input side over 1.1-1.2 micron range and output side over 2.6-11 micron range.

 

BBAR coating is designed to minimise dispersion of ultrashort pulses and also features high damage threshold. Typical reflection values are R<0.5% in the mid range, and up to reflection values of uncoated crystal at the edges of given range.
