Y-LASER Successfully Delivered HELIOS Laser
In ultrafast laser technology, optical parametric chirped-pulse amplification (OPCPA) systems serve as a powerful gain mechanism, playing an important role in the generation of high-precision, broadband ultrafast pulses. An OPCPA system typically consists of two key components: the signal light source and the pump light source. As the core of the signal light source, the seed laser's stability, spectral characteristics, and pulse quality directly determine the overall performance of the OPCPA system. The seed laser must not only maintain precise temporal characteristics during pulse transmission but also work in perfect synchronization with the pump light source to ensure an efficient amplification process.
In the OPCPA system at the Attosecond Research Institute, the pump laser is required to deliver a high-energy, high-repetition-rate, and stable light source to ensure efficient gain and high-quality output from the OPCPA. To meet these stringent demands, we introduce the HELIOS laser as an ideal seed source for your OPCPA system, providing robust support for your ultrafast laser setup.
