Abstract

A high average power tunable laser system that can easily be accommodated in an operating room is described. Seventeen watts of TEM₀₀ average power at 630 nm with a dye lifetime of thousands of watt-hours or hundreds of thousands of photons of pump laser power per molecule of dye has been achieved. This was accomplished at a repetition rate of 25 kHz with a wall plug efficiency of .33%. The system utilizes the high efficiency KTiOPO₄ (KTP) frequency doubled Nd:YAG laser to pump a tunable dye laser system designed specifically for low maintenance and high reliability required in photodynamic therapy. Seventeen watts of TEM₀₀ average power at 577 nm with rhodamine 6G (R6G) was also obtained. Comparison to other high average power tunable systems as well as long term system performance including dye stability data are presented.
