All solid-state room temperature Er:YAG laser operating at 1617 nm

Fiber laser pumped Er:YAG laser action at 1617 nm was achieved at room temperature. An etalon was utilized for tuning the laser to the 1617 nm line. Room temperature operation was characterized and compared with 1645 nm operation. Output power close to 3 Watts CW was demonstrated at the 1617 nm laser line.
