Abstract :
The authors report the power enhancement of a high-repetition-rate TEA-13C18O2 laser by substitution of rare 15N2 isotope instead of 14N2 and its tunable single-mode operation. Efficient, high-power operation with a maximum average power of 25 W (100 Hz) at a slope efficiency of 5.6%, which is improved by a factor of 2 by substitution of 15N2 instead of 14N2, has been successfully achieved from a discharge volume of 57.5 cm3 with an active length of 26 cm. In addition, high-power, tunable, single-mode operation has been achieved with a three-mirror cavity consisting of two mirrors and a Littrow grating
