ABSTRACT:
An improved monoblock laser cavity is made by elongating the Optical parametric oscillation (OPO) cavity. This can be accomplished by changing the coatings on the OPO material and Q-switch and by elongating the OPO cavity to approximately 2 to 3 times the OPO crystal length. The increase in the length of the OPO cavity will improve the beam divergence of the laser.
