Tunable directly diode-pumped continuous-wave room-temperature Cr4+:YAG laser

We report the first demonstration of the diode-pumped tunable cw roomtemperature Cr4+:YAG directly pumped at 970 - 1004 nm by two 2 W diode-arrays. The laser could be tuned from 1420 to 1530 nm and delivered 80 mW of output power at 1.9W of absorbed power.
