Demonstrating a 300 mJ EO Q-Switched 2.79 µm Cr:Er:YSGG Laser
A team of researchers demonstrated that langasite (LGS) enables efficient Q-switch operation of Cr:Er:YSGG lasers at 2.79 µm. The laser is flash lamp-pumped and electro-optically (EO) Q-switched. They report 300 mJ output energy at 15 ns pulse duration at a 3Hz repetition rate, which is, as far as the team knows, the record result documented … Continue reading
