FLINT

Description

The FLINT oscillator is based on Yb:KGW crystal end-pumping by high brightness laser diode module. Generation of femtosecond pulses is provided by Kerr lens modelocking, which is induced by perturbation of the cavity length. Once started, modelocking remains stable over long period of time and is immune to minor mechanical impact. Chirped mirrors and a prism pair are used in a laser cavity to adjust precisely the group velocity dispersion and cavity length.  

The oscillator can also be equipped with Carrier Envelope Phase (CEP) stabilization system.
 
Oscillator module is machined from a single monolithic aluminium block which is being cooled by water to ensure stable and robust operation. The housing of oscillator has two separate sections: cavity section and pump module section on the opposite side. Detector module, which includes a photodiode for oscillator power monitoring, is attached to the front side. The oscillator is contained in the external casing in order to reduce the impact of the environmental temperature on the performance. The special design of external casing includes three point kinematic mounts which are used to support oscillator preventing any mechanical stress caused by difference of thermal expansion between optical table and laser housing. 

FLINT oscillator can be equipped with optional, wavelength converter (HIRO) providing harmonics radiation at 517 nm, 345 nm and 258 nm wavelengths.
 

Feature

  • First choice for seeding Yb based ultrashort pulse amplifiers
  • Excellent pulse contrast due the high nonlinearity inherent for optical Kerr effect
  • Extremely high output power in the range of few watts (standard pulse energy up to 130 nJ at 76 MHz)
  • Ideal source for broadband terahertz generation
  • Spectrum bandwidth broad enough for seeding simultaneously Yb and Nd based laser sources in OPCPA systems
  • Optional CEP stabilization
  • Possibility to lock output pulse phase to external clock
  • Sub-100 fs pulses directly from the cavity of the laser without any additional external pulse compressors
