Material General Description
Nonlinear crystals are indispensable components in advanced photonics systems, enabling efficient wavelength conversion through second-harmonic generation (SHG), sum/difference frequency generation (SFG/DFG), and optical parametric oscillators (OPOs). With superior optical clarity, high laser damage thresholds, and excellent phase-matching properties, these crystals are integral for research, industrial, and medical laser applications. POC offers a range of nonlinear crystals, including LBO, BBO, KTP, and others, all fabricated with precision to ensure reliable performance.
Applications and Examples
- Frequency Doubling (SHG): LBO crystals efficiently double the frequency of Nd:YAG lasers for green light generation (532 nm).
- Optical Parametric Oscillators (OPOs): BBO crystals are used in tunable mid-infrared laser systems for spectroscopy.
- Terahertz Generation: KTP crystals facilitate terahertz wave production for security and imaging applications.
- Pulse Compression: High-damage-threshold crystals enable ultrafast pulse compression in femtosecond lasers.
