摘要：

A single-mode, diode-pumped Tm:YAG laser which is tunable from 2005 to 2035 nm and has an output power of 90 mW at 148 THz (2022 nm) is described. The beat between the frequency of this laser and the fifth harmonic of a CO2 laser transition has been observed using a tungsten-nickel point-contact diode. A signal to noise ratio of up to 20 dB in a 100 kHz bandwidth has been obtained. The Tm:YAG laser will be used as an intermediate frequency source in a chain between a visible frequency and a cesium standard. (C) 1997 Published by Elsevier Science B.V.
