Second and Third Harmonic Generators
 |
PriTel’s SHG/THG Series of Second/Third Harmonic Generators with Integrated Amplifiers can be used in a variety of research applications at 764-782 nm and 510-520nm that include telecom, biomedical, microscopy and materials sciences.
The SHG/THG Series is designed to be used with PriTel’s FFL Series of easy-to-use passively mode-locked fiber lasers that provide polarization maintaining, high peak power pulses at 1528 -1565 nm with pulsewidths from 10 ps to 0.1 ps. The addition of the SHG/THG-FA (with a temperature-controlled section containing periodically-poled LiNbO3) to the FFL yields frequency-doubled (or tripled) pulses from 764 to 782 nm (or 510-520nm) at relatively high power.

Dual function fiber-coupler allows for both free space and fiber coupled outputs. |
The FFL and SHG/THG-FA are easy to use with no external equipment required. The optics are fiber-based, and no alignment is required. The reconfigurable output module can be used for both free space and fiber coupled outputs. This makes the FFL-SHG/THG-FA system a very valuable tool in the research laboratory.
