Ti:Sapphire Lasers

摘要

Ti:sapphire has enabled tunable high-efficiency and high-power laser systems. High figure of merit (FOM) crystals for oscillators have been grown by the CZ-method and heat exchange method (HEM). For multipass amplifiers, however, crystals require higher single-pass-gain rather than high FOM. In this presentation, we will describe new crystal-growthrntechniques, which produce high-gain and high-concentration crystals.
