High Energy OPCPA Systems



  • Up to 45 mJ of output energy at 1 kHz
  • Front end is based on field-proven PHAROS laser
  • Passive CEP stabilization with a temperature stabilized Optical Parametric Amplifier (OPA)
  • High temporal contrast in picosecond time scale


Light Conversion (together with partners) introduces new custom OPCPA system, which provides ultra-short light pulses of high energy (up to 45 mJ) and high average power (up to 45 W). Our OPCPA technology is based on years of experience in developing and manufacturing of Collinear and Non-Collinear Optical Parametric Amplifiers as well as Femtosecond Lasers, and is able to offer leading solutions, such as passive carrier envelope phase (CEP) stabilization. High temporal contrast in picosecond time scale is achieved by using the femtosecond PHAROS pump and the seed derived from white-light continuum. PHAROS oscillator has enough bandwidth for direct seeding of high energy picosecond Nd:YAG lasers.

4.5 TW, 1 kHz OPCPA for ELI-ALPS

Light Conversion and EKSPLA Consortium have won the public procurement tender of the ELI-ALPS facility for the design and construction work for the SYLOS laser system. To our knowledge, the SYLOS laser system will be able to generate four times higher peak power pulses than the current state of the art at 1 kHz rep rate. The system is based on Light Conversion’s Optical Parametric Chirped Pulse Amplifiers driven by Light Conversion’s femtosecond (fs) laser PHAROS and EKSPLA’s picosecond laser.

PHAROS pumps two fs OPAs: the first (FS-OPA) produces passively CEP stabilized pulse at 1.3 µm used for generation of CEP stable WLC, while the second (FS-NOPA) amplifies WLC in 700 – 1000 nm range providing high contrast seed pulse for the subsequent OPCPA stages. The pulse amplified to 50 mJ of energy at an 850 nm central wavelength will be compressed in a sequence of glass blocks and chirped mirrors down to 10 fs pulse duration.
