Abstract:
1. A diode pumped intracavity converting laser, comprising: at least two reflector mirrors defining a resonator cavity at a fundamental wavelength; a first Nd-doped gain medium positioned in the resonator cavity, producing radiation at said fundamental wavelength, a first diode pump supplying pump beam of up to a maximum power at a pump wavelength to the gain medium, at least one harmonic wavelength generator situated within said resonant cavity and optically coupled to it through at least one dichroically coated optic, an outcoupler extracting a desired harmonic wavelength without damage to optical components within said cavity; said resonator cavity and gain medium adapted to operate in a TEM00 mode with a thermal lens in the cavity that is less than 12 D at all pump power levels up to said maximum, such that the said fundamental beam diameter in the harmonic wavelength generator decreases as the pump power increases.
