The PARUS femtosecond optical parametric amplifier (OPA) is designed as a robust automated wavelength conversion tool with
broad wavelength tuning. The units can be pumped either by a Ti:S REUS amplifier series (at ~800 nm) or by Yb ANTAUS or TETA
series (at ~1030 nm).
Certain OPA models include a built-in SHG module for pump beam conversion in order to offer higher energy in the VIS and NIR
ranges, while some models are pumped by a fundamental pump beam offering broader coverage and higher pulse energy in the
MIR range and DFG applications. The system is fully automated and is offered with a Windows PC software for wavelength tuning.
- Generator of the second harmonics of signal and idle frequencies.
- Differential frequency generator.
