Abstract--A novel and compact Er-Yb: glass laser was de-
veloped with single-frequency output power 10 mW in a
wavelength range from 1531 to 1547 nm. The laser output was
efficiently frequency doubled at 770.1 nm in a single-pass peri-
odically poled lithium niobate waveguide and a second harmonic
power in excess of 15 W was achieved, with an internal con-
version efficiency of 220% W 1. This frequency-doubled
beam was used for high-resolution saturated spectroscopy of the
39K 4S1 2-4P1 2 absorption line. The best resolved crossover
peak showed 16% line contrast and 10-MHz linewidth. In a
second experiment, working at the fundamental frequency, satu-
ration spectroscopy of 13C2H2 was achieved using a low-pressure
