Resumen
Optical channel waveguides have been produced in Nd:LGS
laser crystals by using ultrafast laser inscription with a depressed cladding
configuration. The cross sectional shape of the cladding waveguides is
circular, surrounded by low refractive index tracks, which makes the
channel waveguides as three-dimensional tubular structures. Under optical
pump of 810 nm light, continuous-wave waveguide lasers at 1068 nm have
been achieved at room temperature, with minimum lasing threshold of 54
mW, a maximum slope efficiency of 24% and a maximum output power of
16 mW.
