We demonstrate high-efficient CW thin disk 15%Tm:KYW laser pumped by a 20W CW laser diode bar at 803nm. Three 15%Tm:KYW b-cut disks of 200, 250 and 300&mgr;m thickness are tested, with the maximal laser output being of 4.9W at ~1.9&mgr;m. Slope and optical-to-optical conversion efficiencies are reported as well.
