Optical frequency comb set-up: on the two black breadbords there are the 10 GHz mode-locked laser, two optical amplifiers and a frequency mixer for carrier-envelope-offset stabilization; in the background another optical amplifier and a supercontinuum light generation module.
The compact all-in-fiber setup ensures allignment-free and stable operations.

Optical frequency comb supercontinuum spectrum, covering most of GIANO spectral bandwidth with 10 GHz comb modes separation.
