    摘要: general model has been developed for the optimization
    of fiber-coupled laser-diode pumped lasers by including
    the effect of pump-beam quality into the mode-overlap integrals.
    The numerical results of the mode-overlap integrals have been
    fitted to an analytical function of pump spot size, laser mode
    size and the parameter p, which is in terms of laser-diode beam
    quality and properties of the active medium. This analytical
    function allowed us to obtain explicit formulae for the threshold
    pump power, the slope efficiency, and the optimum pump spot
    size. With these formulae, the optimum mode size and the
    maximum output efficiency can be easily calculated for arbitrary
    values of /3 and input power. From the numerical results, we
    obtained an analytical expression to relate the required input
    power and pump-beam quality to the desired output efficiency
    and properties of an active medium. The present model provides
    a straightforward procedure to design the laser resonator and the
    optical coupling system for optimization. To illustrate the utility
    of the present model, a Nd:YAG laser pumped by fiber-coupled
    laser diodes is considered and optimized.
