Pn. Kean et al., GENERATION OF 20 MW OF BLUE LASER-RADIATION FROM A DIODE-PUMPED SUM-FREQUENCY LASER, Applied physics letters, 63(3), 1993, pp. 302-304
Resonant intracavity sum-frequency mixing of a diode-pumped Nd:yAG las
er and a 100 mW single stripe laser diode, has been used to generate a
measured output power of 20 mW of blue laser radiation at 459 nm. Thi
s represents a total conversion efficiency of approximately 68% of the
single stripe laser diode power incident on the cavity. The laser was
also demonstrated to operate over a tuning range of 12 nm via angle t
uning of the nonlinear crystal.
