Scott Diddams and his colleagues at NIST, the University of Colorado, and Menhir Photonics published a paper characterizing a 1 GHz frequency comb based on a Menhir-1550 mode-locked laser. ƒ_CEO was shown to have residual phase noise of 438 mrad and ƒ_opt residual phase noise was 40.6 mrad.

Menhir Photonics femtosecond laser sources are based on robust and well-engineered designs, offering excellent reliability with the low-noise performance from soliton mode-locking. Robust, 24/7 operation, user-friendly and self-starting, the MENHIR-1550 series has been made to facilitate OEM integration and enable customers applications.

The Menhir-1550 provides control capability over the repetition rate and carrier envelope offset and so it can serve as the engine for a high-repetition rate frequency comb.

Need 100-200 MHz repetition rate, broader bandwidth, shorter pulses, matched repetition rates?  We offer the MLL-100.  And fully stabilized frequency comb performance is available from the FFC-100.
