Super-stable visible diode laser

Visible diode lasers best for biomedical application spectroscopic anaysis are now available.  External cavity configuration gives ±1nm wavelength accuracy and <0.2nm stablity with gaussian sigle mode beam from PM fiber.


The Best seed source for pulsed fiber laser

HK-5630 is an ideal seed source for pulsed MOPA fiber laser and a range finder. It outputs a pulse as short as 1.5ns from PANDA fiber in a tiny CAN package without any chirping in any driving conditions.
