Product Description

ZGP

Zinc Germanium Phosphide crystal is an efficient mid-infrared nonlinear optical crystal material. Its transparency range is from 0.76 to 12.0 µm, making it suitable for applications in the mid-infrared spectral region such as optical parametric amplifiers (OPA), optical parametric oscillators (OPO), second-harmonic generation (SHG), and fourth-harmonic generation (FHG).
 

Applications

1. Generating mid-wave and long-wave infrared continuously tunable radiation with OPO and DFG techniques
2. Harmonic generation based on CO2 and CO lasers
3. Generation of terahertz frequency

 

Features

1. Transmittance range from 2µm to 12µm
2. Relatively high damage threshold
3. High thermal conductivity
4. Broad phase matching spectral range
