Abstract
In this work, we present for the first time a method for quasi-smooth tuning of the second harmonic radiation of an Nd:YVO4/LBO laser within a 60-GHz range. Practicality of this method is demonstrated at the radiation output power of 1.5 W at 532 nm. The proposed method features automatic stitching of 12-GHz continuously tuneable ranges to the precision of the laser output line width (5 MHz). The stitching does not require a precision wavelength meter and is based on a high-finesse scanning confocal interferometer.
