Abstract

This paper explains the tunable 214.5-nm continuous-wave coherent radiation generated by using an all-solidstatelight source system. The light source consists of the oscillator and amplifier system based on laser diodesand the two-stage frequency doubling system with KNbO₃ and β-BaB₂O₄ crystals. The power of the generated 214.5-nm light amounts to more than 0.64 mW. This light source will be used for laser-cooling of Cd⁺ ions.
