In this paper we demonstrated and analyzed a high-power cw Nd:CNGG laser end-pumped by a ÿber-coupled diode laser array in a convex-concave-type cavity. TEM00 mode output power of 1:63 W was obtained with 27% optical-to-optical conversion e ciency and slope e ciency of 44.5%. Thermal lensing and its

Gas temperature and water concentration are measured by a tunable diode laser sensor using a single laser near 1.4 m. Temperature is determined from the ratio of absorption of a H 2 O line pair near 7079.176 and 7079.855 cm -1 , which are chosen using some selected criteria. The second harmonic dete
