摘要
Optical frequency doubling apparatus is disclosed having a system output portion and a source of coherent radiation together with a plurality of discreet nonlinear light transmissive devices positioned in series between the source of coherent radiation and the system output portion, and further including a phase shifter positioned in series with the nonlinear light transmissive devices for altering the phase of light wavefronts passing therethrough. A harmonic beamsplitter is used to separate the frequency doubled output from the coherent light inputted into the system by the source of coherent radiation.
