BBO for THG (Third Harmonic Generation)Request for Quotation >
Is a nonlinear crystal that offers several unique and very important characteristics
BBO material is widely recognized for these features:
- Very wide transparency
- Moderately high nonlinear coupling
- High damage threshold
- Good chemical and mechanical properties
Third Harmonic Generation (THG) is a process whereby light is generated at a wavelength which is 1/3 of the pump wavelength, and it is achieved by a two stage interaction. The first stage is SHG of the pumping laser. The second stage is Sum-Frequency Generation of the pump and second harmonic, yielding the third harmonic.
