Abstract

The diode-pumped Nd:KYW laser operated in the free-running mode at 1072 nm is demonstrated at room temperature. The laser output power of 102.6 mW with 12.07% optical-to-optical conversion efficiency and 13.16% slope efficiency is obtained. The laser threshold is about 110 mW. Such a low threshold is in agreement with the theoretical prediction.
