Menhir-1550 phase noise graph

Low phase noise of the 250 MHz and 1 GHz models


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 have a solution for that.

Vescent is the exclusive Distributor of Menhir products in the US and Canada. For more information, visit the Menhir site.
