GaSe – Gallium selenide
0.9 µm - 16 µm
Gallium selenide (GaSe) is a hexagonal crystal primarily used for second harmonic generation (SHG) in the far-infrared (FIR) wavelength range. Due to its extremely low Mohs hardness, GaSe is very fragile, making mechanical treatments or coatings impractical. 3photon offers GaSe crystals cut along the optical Z-axis with cleaved surfaces.
- Applications
- Features
GaSe is ideal for electronic and optical applications.
- High-power femtosecond lasers
- Terahertz (THz) generation
- Alternative solution for generating broadband mid-infrared (MIR) electromagnetic waves
- Second harmonic generation (SHG) in mid-infrared (MIR) for CO, CO₂, dye lasers, and more
- Up-conversion from infrared (IR) to near-infrared (NIR) range
- Optical parametric generation (OPG) in the 3–16 µm range
- GaSe is a very soft material, making polishing or coating procedures infeasible.
- Transparency range: 900–16,000 nm
- Can only be cut along the (001) plane
- Only small Theta angles are usable due to the high refractive index and orientation constraints
- A cost-effective alternative to AGS or AGSe for generating 2400–20,000 nm or terahertz (THz) output
