摘要: A Cr4+:YAG passively Q-switched Nd:YVO4 microchip laser for versatile controllable transverse modes has been demonstrated by adjusting the position of crystal along tilted pump beam direction. The diameter-dependent asymmetric saturated inversion population inside governs oscillation various Laguerre–Gaussian, Ince–Gaussian and Hermite–Gaussian modes. Controllable with repetition rates over 25 kHz up to 183 kHz, depending on crystal, have achieved. beams a nanosecond pulse width peak power hundreds watts obtained potential applications in optical trapping quantum computation.
