Non-Linear Crystals

Electro-optics

Non-Linear Crystals from 3Photon enable efficient frequency conversion and ultrafast laser applications, offering high optical quality and reliable performance for advanced photonics systems.

3Photon provides a comprehensive portfolio of non-linear optical crystals designed for demanding laser and photonics applications where efficient wavelength conversion, stability, and precision are essential. These crystals form the core of modern laser systems used in scientific research, industrial processing, spectroscopy, and quantum technologies.

Non-linear crystals exploit intensity-dependent optical properties to enable processes such as second-harmonic generation (SHG), sum- and difference-frequency generation, and optical parametric oscillation (OPO). 3Photon’s crystals are carefully grown, oriented, and finished to deliver high conversion efficiency, low optical loss, and excellent damage resistance, even under high peak power and ultrafast laser operation.

High Performance for Advanced Frequency Conversion

3Photon non-linear crystals are engineered to support a wide range of laser sources - rom continuous-wave to ultrafast femtosecond systems. Optimized phase-matching, tight crystallographic tolerances, and precise cutting ensure stable and repeatable performance across applications.

Available crystal types and configurations support:

Efficient harmonic generation (e.g. SHG, THG)
Tunable wavelength generation using OPO and OPA systems
Broadband and narrowband operation depending on system requirements

Quality, Customization, and Reliability

Each crystal is produced with strict quality control to ensure optical homogeneity, low scatter, and accurate orientation. Anti-reflection coatings can be applied to maximize transmission and minimize Fresnel losses at specific wavelengths and angles of incidence.

3Photon offers both standard crystals and custom-engineered solutions, allowing system designers to optimize performance for specific wavelengths, pulse durations, and power levels.

What are non-linear crystals?

They are special optical crystals that change light’s properties (like frequency/color) when intense light - such as from a laser - passes through them. This enables effects like frequency conversion, where one wavelength can be turned into another.

Which applications use nonlinear crystals most?

Industrial lasers, scientific research, medical systems, spectroscopy, and photonics instrumentation.

What advantages do 3Photon nonlinear crystals offer?

High conversion efficiency, optical stability, and consistent quality for reliable laser performance.

How do nonlinear crystals improve laser system flexibility?

They enable access to new wavelengths without changing the primary laser source.

Do these crystals need special mounting or handling?

Yes - high-precision nonlinear crystals often require careful mounting to ensure proper phase matching and avoid damage. Many are shipped unmounted so customers can integrate them into optical systems as needed.
