摘要
An actively Q-switched laser based on UV illumination mitigates pyroelectric effects in lithium niobate. An exemplary embodiment comprises a pump source; a dichroic mirror having one end optically facing said pump source; a gain medium optically facing another end of said dichroic mirror; a polarizer having one end optically facing another end of said gain medium; a quarter wave plate having one end optically facing another end of said polarizer; and a electro-optic crystal having one end optically facing said quarter wave plate, at least one side of said electro-optic crystal being electrically connected to Q-switch driver to have the crystal function as a Q-switch. A UV illumination source illuminates a side surface of said electrical-optic crystal with UV light. An output mirror receives an output from said Q-switch and produces a laser emission.
