Compact, Few-cycle, CEP-stable OPCPA Systems
- Few-cycle pulses in a compact footprint
- Industrial-grade pump: up to 480 W, 20 mJ
- High repetition rate, up to MHz
- High-contrast variable-bandwidth seed source for CPA and OPCPA systems
- CEP stabilization option
Benefiting from the industrial-grade stability and reliability of CARBIDE and PHAROS femtosecond lasers, ORPHEUS-OPCPA delivers few-cycle, CEP-stable pulses in a compact design, similar in size to our standard parametric amplifiers.
All ORPHEUS-OPCPA models use the same base architecture to generate CEP‑stable, high-contrast, few-cycle pulses at different fixed output wavelengths, including but not limited to 800 nm, 1050 nm, 1600 nm, or 2000 nm. ORPHEUS-OPCPA is available with or without a pulse compressor, thus intended as seed sources, delivering background-free pulses with near‑single-cycle bandwidths, excellent spectral phase coherence, and CEP stability.
When synchronized with industrial-grade CARBIDE or PHAROS femtosecond lasers, ORPHEUS-OPCPA achieves pump power of up to 480 W and pump pulse energy of up to 20 mJ. Higher power operation using alternative pump sources, such as thin-disk or innoslab lasers, is available upon request.
