Abstract
ALPhANOV has developed expertise around the interfacing and integration of specialty optical fibers. We propose to present new developments concerning 100W-class fiber laser based on Yb-doped Large Mode Area fiber amplifier and a new plug-and-play connector for ultrashort pulse beam delivery by using Hollow Core Photonic Crystal Fibers. In terms of high power fiber amplifier, we recently developed a high performance, fully monolithic PCF amplifier module. The module is based on the DC-200/40-PZ-Yb of NKT Photonics and on a homemade fiber fused component allowing us to couple up to 6 pumps of 50 W at 976 nm together with 5 W of signal, leading to an achieved power of 210 W at 1064 nm, which is to the best of our knowledge the highest power ever delivered by a fully monolithic PCF amplifier. The module is entirely thermally controlled in a rugged package and has run more than 100 days at > 100W average power with an excellent power stability < 1%. Concerning fiber beam delivery solution, hollow core photonic crystal fiber has shown great potential for an industrial solution. To penetrate the industry, high power femtosecond lasers need low-loss stable and plug-and-play connectors to couple light into hollow-core single-mode fibers and carry it to the target. We recently developed such connector and tested it on different industrial femtosecond laser, 50W and 100W class. The new design of the connector compatible with vacuum or noble gas and 300W class femtosecond laser will also be presented.
