Automatic phase-matched frequency-doubling system for the 240-350-nm region.
An automatic frequency-doubling system has been constructed using a lithium formate monohydrate crystal as the frequency doubler in a stationary optical arrangement. Without any readjustment of the crystal orientation, smooth tuning of the uv light over the 240-350-nm range has been obtained. The feasibility of this system for uv absorption measurements has been successfully demonstrated using S0(2) gas.
