Narrow Linewidth CW and Pulsed Mode-Locked Lasers

D2-100-HP1 High-power DBR laser

D2-100-HP1 high-power DBR laser

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.

Vescent’s MLO Mode-Locked Oscillator 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 MLO-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 MLO-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 MLO-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 MLO-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.

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.
