Flint Series - Femtosecond Ytterbium Oscillators

The FLINT series oscillators stand out by their short pulse duration of 30 fs to 170 fs and the high repetition rate of 76 MHz (optionally 60 - 100 MHz). The output power is up to 20 W. Optionally, the series can be equipped with Second Harmonic Generator or CEP stabilization. The FLINT oscillators are also suitable for pumping the harmonic generator HIRO.

Description 

Features

  • Sub‑40 fs without any additional pulse compressor
  • 250 nJ pulse energy
  • 20 W output power
  • 76 MHz is standard
  • No amplified spontaneous emission
  • Rugged, industrial grade mechanical design
  • Automated harmonic generator (515 nm)
  • Optional CEP stabilization
  • Possibility to lock to external clock

Applications

  • Seeding Yb/Nd based ultrashort pulse laser amplifiers
  • THz generation
  • Two‑photon polymerization
  • Non‑linear microscopy
  • Seeding CEP stabilized laser sources
  • Pumping of femtosecond OPA

The FLINT oscillator is based on Yb crystal pumped by high brightness laser diode module. Generation of femtosecond pulses is provided by Kerr lens mode-locking. Once started, mode-locking remains stable over a long period of time and is immune to minor mechanical impact. Piezo-actuator can be implemented in customized oscillators in order to control the cavity length. FLINT oscillator can also be equipped with Carrier Envelope Phase (CEP) stabilization system.

Locking of the optical pulse to an external signal

Pharos oscillator can be equipped with piezo actuators for precise control of the cavity length.

Carrier Envelope Phase (CEP) stabilization

Pharos oscillator can be equipped with nonlinear interfero­meter and feedback loop throughout the pump current of the laser diode bar for CEP stabilization.

  • Rugged, industrial grade mechanical design

Automated second harmonic generator is integrated in FLINT oscillator when a single output wavelengh is desired. Selection of fundamental (1035 nm) or second harmonic (517 nm) output is available by software control.

In case fundamental and second harmonic outputs are required simultaneously, then stand-alone Hiro harmonic generator is the solution.

Hiro 

Stand-alone Harmonics Generator Hiro

HIRO is a valuable option for PHAROS / CARBIDE lasers and FLINT oscilla­tors that provides high power harmonics radiation at 515 nm, 343 nm and 258 nm wavelengths. We offer several standard HIRO models (with open prospect of future upgrades) which meet most users’ needs. The active harmonic is selected by manual rotation of the knob – changing the harmonics will never take longer than a few seconds thanks to its unique layout and housing construction.

HIRO is the most customizable and upgradable harmonics generator available on the market. It can be easily modified to provide white light continuum, beam splitting / expanding / down‑collimating options integrated in the same housing as well as harmonics splitting that makes all three harmonics available at a time.

Please contact us for customized version of HIRO.
