Characteristics of a High Energy Pump Source for Yb Laser Materials

摘要

Characteristics of a flashlamp pumped Ti:sapphire laser for high intense optical pumping of Yb mateirals was investigated. Emission spectra from the flashlamp was measured by a multi channel spectrometer. Emission below 400 nm was filtered by UV filters. Output energy of 6J/pulse at 800 nm and 2J/pulse at 910 nm were obtained constantly. Wide tuning performance from 730 to 950 nm was demonstrated with the use of a prism and an etalon in the cavity. An efficient UV-visible solid state converter, a broadband quartz birefringent filter and an acoust optic tunable filter would be effective for improving the output energy and the efficiency.
