RAEA

By KMLabs

High power femtosecond IR laser system (e.g. KMLabs RAEA). Because HHG is a high order nonlinear process (e.g. conversion from 790 to 13.5 nm is n = 59), any minor defects in the laser performance will scale exponentially and wreak havoc on EUV generation. For this reason, KMLabs has developed and patented PermacoolTM technology that provides ultrahigh pulse quality from our Ti:Sapphire amplifier systems. Permacool is at the heart of the RAEA, allowing you to push your system harder without having to worry about the thermal lensing effects that can distort your beam in both time and space as depicted in the simplified cartoon below. KMLabs’ expertise in cryogenically cooling Ti:Sapphire crystals have allowed us to fine-tune this technology to make the best use of it for HHG. For instance, KMLabs has observed up to 1000 times more flux at 13.5 nm generation with our cryogenic-cooling technology—even while driving at much lower pulse energies—compared to other commercial solutions that only rely on water-cooling at relatively high room temperature. In addition to providing ultrahigh pulse quality, Permacool also enables repetition rate flexibility, both in flexibility (software control) and in magnitude (with up to 200 kHz demonstrated). Thus, our RAEA amplifier technology provides truly best-in-class performance for applications that require high pulse quality like HHG, where peak focusable intensity is critical.
