AGS-Silver Thiogallate

A premier infrared (IR) material for nonlinear devices (1–12 μm), AGS exhibits exceptional nonlinear coefficients in NIR-IR bands, enabling high-efficiency optical parametric oscillators (OPO), CO/CO₂ laser systems, and IR waveplates. Available in scalable formats from bulk crystals to AR-coated wafers (<0.5% reflectance @3–5 μm), it combines high damage thresholds (>100 MW/cm²) with broad phase-matching capabilities for defense and sensing applications.

Application

Efficient frequency doubling for mid-IR radiation

Non-linear three-wave interactions

Main crystal for DFG system pumped by 1.2-1.6 μm & 1.6-2.4 μm for 2.4 – 11 μm generation

Opto-medical instruments

Spectroscopy applications

High performance infrared (IR) waveplates

2_nd and 3_rd harmonics generation in CO, CO₂ laser systems

Feature

Transparency from 530 nm to 11 µm of 3photon AGS crystals allows different frequency generation and optical parameter oscillation (OPA) in that region

Could be pumped directly by 1064 nm or 1500-1600 nm in OPO systems

AGS has the highest figure of merit for non-linear interactions in the near infrared (NIR) and far infrared (FIR) in comparison to other IR crystals
