Precision Electro-Optic and Laser Technologies

Pulsed and CW Lasers

Made in America!

The FFC-100 from Vescent Photonics is a fully stabilized octave-spanning frequency comb with precise control over ƒrep, ƒopt, and ƒCEO.  It is built around the Vescent MLL-100 Mode-Locked Laser, a stand-alone erbium-based femtosecond MOPA.  A highly non-linear fiber broadens the spectrum and our unique ƒCEO lock detection reduces the size, weight, and power of the system. The complete FFC-100 frequency comb is designed and built to ensure stable, low-phase noise operation with Allan Deviations supporting the next generation of optical atomic clocks.

The FFC-100 was designed for low SWaP and turn-key, stable operation: A single 2U 19” rack mount chassis contains the oscillator, amplifier, pump lasers, supercontinuum generation module, and ƒCEO detection and lock as well as the control electronics.


Vescent’s MLL Mode-Locked Laser is a stand-alone femtosecond laser designed for ease of use and high performance. Built around an Er:doped fiber and an EDFA, it will reliably deliver sub-100 fs pulses with a bandwidth of over 40 nm. The heart of the MLL-100 is our FO-100 Fiber Oscillator including a gain fiber, mode-locker, and our unique cavity length adjustment tool for exact repetition rate control (and matching). The MLL-100 houses the amplifier and pump diodes, current sources and temperature control, as well as the requisite drive electronics and user interface.

Designed for ease of use and performance, the MLL-100’s combination of touch screen interface and rotary knob input makes for simple set up and control. Modulation and control of the pump power as well as fast (via PZT) and slow (via temperature) tuning of the repetition rate makes the MLL-100 ideal as the engine for your frequency comb development. The slow integrator controlling the precise temperature set point allows long-term repetition rate locking when combined with the fast PZT loop.

Menhir-1550 GHz mode-locked laser

The Menhir-1550 Mode-Locked Laser

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.

Our narrow linewidth cw lasers are constructed with no moving parts or piezos and with very short laser cavities. This unique combination of no moving parts and short cavity lengths results in lasers that are incredibly immune to vibrations.  Furthermore, the short cavity means a large free-spectral range for broad mode hop-free tuning.  This means that unlike conventional external cavity diode lasers, our lasers can be injection current tuned over many GHz.  This enables high-speed frequency agility and very fast servo control for locking.  Since the servo feedback can be both fast (many MHz which is much greater than acoustic frequencies) and long range (many GHz of injection current tuning) the locks are especially robust against acoustic or vibration challenges.

Heterodyne Agile Laser (HAL)
The HAL Heterodyne Agile Laser integrates all of the powerful features of the D2 series into a miro-optical platform for SWaP-sensitive applications. The HAL series of atom-referenced, frequency-agile lasers integrates diode laser sources, an alkali metal vapor-based frequency standard, and a heterodyne beat note collection system into a single butterfly package to deliver highly stable tunable light to your quantum sensing devices. Well known for high-speed, low-noise control electronics as well, we provide stand-alone or integrated electronics configurations that will optimize your system with respect to optical performance, space, power consumption, and thermal management requirements. It is possible to customize the HAL for your specific needs, including single- or multiple-laser designs, amplified and shuttered systems, specific form factors, and other wavelengths.
