✦ Synopsis

A three-wavelength pulsed laser for dental application is developed. The laser houses the Nd:YAG resonator (1:06=1:32 m) for soft-tissue treatment and Er:YAG resonator (2:94 m) for caries removal and ÿts and ÿssure treatment. Two heads share the cooling unit and two identical high-voltage power supply modules in order to achieve compactness. The Nd:YAG laser has 10 W at 1:06 m and 7 W at 1:32 m with a pulse duration of 100 s. An Er:YAG laser of 2:94 m has 3:5 W, 20 Hz and a pulse duration of 250 s. The beams are delivered through ÿbers and the laser size is 75 × 55 × 32:5 cm.

Previous investigations have shown good clinical potential for the use of the 1.32 pm wavelength Nd:YAG laser because its soft tissue absorption is better than that of the 1.06 pm wavelength NdYAG laser. The 1.32 pm wavelength NdYAG laser has an absorption coefficient in water that is 10 times highe

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
