Recent developments in the growth and characterization of potassium lithium niobate (KLN) crystals for direct doubling of semiconductor lasers

This paper reports the successful growth of crystals of the potassium lithium niobate (KLN) family having a non-centred tungsten bronze structure. Crack free crystals up to 20 mm in diameter by 30 mm in length have been grown reproducibly by the top-seeded solution growth (TSSG) method from K+ and L...

Summary:This paper reports the successful growth of crystals of the potassium lithium niobate (KLN) family having a non-centred tungsten bronze structure. Crack free crystals up to 20 mm in diameter by 30 mm in length have been grown reproducibly by the top-seeded solution growth (TSSG) method from K+ and Li+ rich solutions. These crystals form solid solutions in which both the structural and optical properties vary with composition. Birefringence measurements show that KLN crystals may be non-critically phase matched for second harmonic generation in the wavelength range 1050 nm to 820 nm at room temperature, depending on composition. The ability to tune the optical properties in this way makes KLN an ideal candidate for direct doubling of semiconductor lasers. © 1998 Chapman & Hall[PUBLICATION ABSTRACT]
