Griffin – Ti:sapphire Oscillator Family

The Griffin™ series is KMLabs’ family of tunable ultrashort-pulsed Ti:sapphire-based oscillators. It is a fully engineered and integrated commercial source based on a single rugged opto-mechanical platform.


The KMLabs Griffin™ series of Ti:sapphire oscillators gives customers ultimate control over their system, are simple to maintain, and offer a wide range of performance specifications enabling many different applications.  These prism-based oscillators use Kerr lens modelocking to generate ultrashort < 12 fs pulses.  All Griffin lasers include computerized control of the spectral bandwidth and center wavelength and water-cooled breadboards for maximum long term stability. There are options within the Griffin series that include integrated pump lasers and diagnostics. Griffin lasers are very simple to maintain, since components are easily accessible.

Key Features:

  • Average powers up to >1.4W
  • Maximum pulse energy >15 nJ
  • Configurable repetition rates from 75-102 MHz
  • Configurable power
  • Computer control of the center wavelength and bandwidth of the oscillator spectrum
  • Computer controlled pulse duration
  • < 12fs standard with < 10fs option
  • Excellent beam quality: M2 typically < 1.2
  • One-box configurationon with integrated pumps
  • Repetion-rate lock option (HalcyonTM)
  • CEP-stabilized option
  • Graphical, intuitive software control with integrated diagnostics
  • Custom configurations available
