DIODE PUMPED, MULTIAXIAL MODE, INTRACAVITY DOUBLED LASER

摘要

A diode pumped, multi axial mode, intracavity doubled, intracavity tripled laser, includes at least two resonator mirrors defining a resonator cavity. A laser crystal (22, 56) and a doubling crystal (36) are positioned in the resonator cavity. A tripling crystal (80) is also positioned in the resonator cavity. A diode pump source supplies a pump beam to the laser crystal and produces a laser crystal beam with a plurality of axial modes that are incident on the doubling crystal. This produces a frequency doubled output beam. Further, a diode pumped, multi axial mode, intracavity nonlinearly converted laser is provided and includes at least two resonator mirrors defining a resonator cavity, a laser crystal and a nonlinear conversion apparatus positioned in the resonator cavity. A nonlinear conversion apparatus is also positioned in the resonator cavity. A diode pump source supplying a pump beam to the laser crystal and produces a laser crystal beam with a plurality of axial modes that are incident on the nonlinear conversion apparatus. The result is a nonlinearly converted output beam that has a % RMS noise of less than 3 %.
