Abstract
A diode pumped, multiaxial mode, intracavity frequency doubled laser resonator has high amplitude stability, meaning that the percent root mean square noise (%RMS) of the doubled output beam power is low. A diode pump source supplies a pump beam to a laser crystal positioned in a resonator cavity and produces a multiaxial mode infrared beam that is incident on a doubling crystal, also positioned in the resonator. A frequency doubled output beam is produced that has an RMS of less than 3%, and in some cases less than 0.2%. The laser is highly efficient, provides high output power, and its output beam is of high spatial quality.
