WHITE DWARF HE
OPCPA

The White Dwarf OPCPA is a powerful femtosecond optical-parametric chirped-pulse amplifier system. It comes as a complete system in different power levels, pumped by an industrial Yb:fiber or Yb:YAG laser, making it robust, reliable and easy-to-use. The different wavelength versions covering the near- to mid-infrared range open a wide field of applications. All versions can be combined to dual output pump-probe systems with different pulse properties in pump and probe output and intrinsic synchronization.
  • high-performance OPCPA system up to 30 W output power
  • pumped by Yb:Fiber or Yb:YAG laser
  • up to 3 mJ input energy
  • compact and versatile
  • < 10 fs pulse duration available

Applications and News

THz generation

Owing to their high second-order nonlinear susceptibility, organic crystals have gained tremendous interest as THz generators within the scientific community. The phase matching condition is best fullfilled when the pump wavelength is in the IR range from 1400 nm to 1700 nm.  The absorption of the pump light in the crystals is reduced in this wavelength region, leading to an increased damage threshold, which enables higher pump fluences and hence a higher conversion efficiency.
