Note: The FFL Series offers front-panel electrical sync pulse output for synchronizing the optical pulse train to an external system.
* For pulsewidths shorter than 700 fs, the laser may not be mode-locked throughout the entire wavelength range. ** Defined as short-term, pulse-to-pulse jitter.

PriTel's FFLs are passively mode-locked fiber lasers that
generate soliton pulses without using any external clock
or reference source.  These lasers are very easy to use.

The pulse-repetition rate is based simply on the transit
time of the pulse in the fiber laser cavity.  The pulse is
shaped by an internal saturable absorber.  To operate
the FFL, just turn on the key switch.  No further
adjustments are necessary.

The following outputs are standard on PriTel's FFLs:
 primary PM optical output
 secondary non-PM optical output (provides
    approximately 10% of the primary output power
    and is useful for measuring pulsewidth or pulse spectra)
  RF electrical output from an internal photodiode
    (useful for synchronizing other equipment in the experiment)

Quick-Change Pulsewidth
PriTel's Quick-Change Pulsewidth feature is standard on
every FFL model with a pulsewidth greater than 150 fs.
Each filter is designed to optimize the optical spectrum and
pulse shape for the pulsewidth selected.

A kit of three standard cartridges is available at a discount.
Please inquire about cartridges for special pulsewidths.
