Second Harmonic Generators

In response to customer requests, PriTel now provides
a Second Harmonic Generator for a variety of research
applications at 765 to 780 nm in telecom, biomedical,
microscopy and materials sciences.

PriTel’s FFL Series of passively mode-locked lasers are
easy-to-use fiber lasers that provide polarization maintaining,
high peak power pulses at 1530 -1565 nm with pulsewidths
from 7 ps to 0.6 ps.  The addition of a temperature-controlled
module containing periodically-poled LiNbO3 yields frequency-
doubled pulses from 765 to 780 nm.

The FFL fundamental source is easy to use with no external
equipment required.  The optics are fiber-based; therefore,
no alignment is required. This makes the FFL-SHG system
a very valuable tool in the research laboratory.
