ps blue light at 488. 5nm generated by frequency doubling with a KNbO3crystal
Using a KNbO3 crystal of 6.9×5.3×3.3mm3 size tunable blue light at 485 -493nm was generated by frequency doubling of the tunable near IR output from an optical parametric amplifier. The energy conversion efficiency at 488.5nm has been measured to be 2.6%, and the peak power over 2kW.
