High power tunable UV coherent radiation has been achieved by sum-frequency generation(SFG)inβ-BaB_(2)O_(4)(BBO) crystal.The maximum output power obtained is about SMW(near 368nm)and 0.75MW(near 222.5nm)
We report the operation of aβ-BaB_(2)O_(4)(BBO)optical parametric oscillator(OPO)broadly tunable in the visible and the near infrared.Quantum efficiency of 22.7%for the signal and 34.1%for the idler corresponding to ...We report the operation of aβ-BaB_(2)O_(4)(BBO)optical parametric oscillator(OPO)broadly tunable in the visible and the near infrared.Quantum efficiency of 22.7%for the signal and 34.1%for the idler corresponding to the total energy conversion efficiency of 25.9%has been achieved.The maximum average output power and the maximum output energy reached 220m W and 22rnJ/pulse,respectively.By changing the matching angle of the OPO,the output wavelength was continuously scanned throughout 425-2144nm.展开更多
