REDUCTION OF SURFACE HEATING EFFECTS IN NONLINEAR CRYSTALS FOR HIGH POWER FREQUENCY CONVERSION OF LASER LIGHT |
摘要 |
A device for generating a frequency converted laser beam includes a nonlinear crystal having a first end face and a second end face opposed to the first end face. The nonlinear crystal is configured to receive at least one input laser beam at the first end face and output a frequency converted beam at the second face. A beam waist of the at least one input laser beam is positioned between the first end face and the second end face during a frequency conversion process. The device also includes a second crystal having a first end face bonded to the second end face of the nonlinear crystal and a second end face opposed to the first end face. A beam diameter of the frequency converted beam at the first end face of the second crystal is less than a beam diameter of the frequency converted beam at the second end face of the second crystal.
