HIGH-POWER FREQUENCY CONVERSION APPARATUS USING A MULTI-PASS CONJUGATE-IMAGE SUB-CAVITY DESIGN

摘要

A frequency conversion apparatus employing a multi-pass conjugate image sub-cavity design is disclosed. The frequency conversion apparatus (100) comprises a fundamental wave resonator (10) for generating a wave, the fundamental wave resonator including first and second end mirrors (12, 14), a laser medium (16), and an energy source (15); a first sub-cavity (11) located at least partially within the fundamental wave resonator, a first frequency conversion medium (26) for converting a portion of a fundamental wave into the first converted wave; and a second frequency conversion medium (28) for generating at least a second converted wave having a frequency that is different from the first converted wave, the second frequency conversion medium located within the first sub-cavity.
