MLL-100 Mode-Locked Laser is a stable, all-fiber source of sub-100 fs pulses.  High-banwidth control over oscillator pump power and cavity length allow for stabilization of ƒCEO and ƒopt or ƒrep.

MLL-100 Mode-Locked Laser

MLO-100 Mode-Locked sub-100 femtosecond Oscillator

Vescent’s MLL-100 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 and slow 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.

Designed for performance, the MLL-100 accepts a user-supplied pump input.  Modulation and control of the pump power as well as fast (PZT) and slow (temperature) tuning of the cavity lenngth makes the FO-100 ideal as the engine for frequency comb development.
