Abstract

The expanding field of LD-pumped solid state lasers forms an extraordinary challenge for developing the optical coatings. Optical thin films for LD-pumped Nd:YVO₄/LBO blue laser at 457nm was presented in this paper based on lower gain laser line action theory, including spectral beam dividers and doubling antireflecting multilayer coatings. To achieve 914nm laser action and 457nm blue light high output power, the coating specifications of laser resonator was analyzed. The transmittance/reflectance spectrum request was effectively separated by adopting high tuned radio stack, simultaneously the spectrum request was reasonably distributed on the two resonator facet reflectivity for restrain the other laser lines such as 1064nm and 1342nm. The dielectric high reflective laser mirror and antireflecting coatings for 457nm laser were manufactured by double ion beam sputtering technique, which is controlled by a time-power monitoring. Using type-I critical phase-matching LBO crystal, 457nm blue laser is obtained by 914nm intracavity frequency doubling. The maximum laser output power of 1.5W is obtained when incident pump laser of 15W is used.
