M-Comb
(Femtosecond Fiber Laser 1560 nm, 1040 nm)
Versatile Core of Frequency Comb Systems, Offering Large Comb Mode Spacing and High Optical Power Per Mode.
Menlo Systems‘ fiber based femtosecond laser sources integrate the latest achievements in fiber technology into easy-to-use products.
Both the M-Comb and orange-Comb feature polarization maintaining outputs, ensuring excellent stability.
The lasers are maintenance free and ready to use at the press of a single button.
Engineered for the most demanding scientific applications, both lasers feature actuators for the laser repetition rate and the carrier envelope offset frequency required for high bandwidth PLLs as well as for extended tuning ranges.
Customize your laser with the available options to match the requirements of your application.
