  • With the optical axis of the second BBO crystal twice the phase matching angle relative to the first one in LD-pumped intracavity doubling solid-state Nd:YAG/BBO blue laser,walk-off effect has been compensated and the beam quality has been improved.When each BBO crystal is 1.5 times longer than the effective interaction length,the output beam of the Nd:YAG/BBO/BBO laser is still circular and the ellipticity is 0.99.

Abstract: With the optical axis of the second BBO crystal twice the phase matching angle relative to the first one in LD-pumped intracavity doubling solid-state Nd:YAG/BBO blue laser,walk-off effect has been compensated and the beam quality has been improved.When each BBO crystal is 1.5 times longer than the effective interaction length,the output beam of the Nd:YAG/BBO/BBO laser is still circular and the ellipticity is 0.99.
