N2 - Compact CW lasers in the visible spectral region are of great importance for vast number of applications including biophotonics, photomedicine, spectroscopy and confocal microscopy. Currently, commercially available lasers of this spectral region are bulky, expensive and inconvenient in use. Also, there is a lack of diode lasers emitting in the visible spectral range, particularly in the yellow region, where a range of important fluorescent probes are optimally excited. An attractive way to realize a compact yellow laser source is second harmonic generation (SHG) in a periodically poled nonlinear crystal containing a waveguide which allows high-efficient frequency conversion even at moderate power level. In this respect, periodically poled lithium niobate (PPLN) waveguided crystal is one of the best candidates for efficient SHG. In recent years, the progress made with the fabrication of good quality waveguides in PPLN crystals in combination with availability of low-cost, good quality semiconductor diode lasers, offering the coverage of a broad spectral range between 1 µm and 1.3 µm, allows compact CW laser sources in the visible spectral region to be realized.
