如果允许活性原子之间的弹性和/或共振碰撞,则气体激光器中的反转密度的表达式包括附加项。该项是线参数γ1和γ2的函数,并且描述了均匀加宽对饱和增益分布的影响。这些参数的测量表明,在0.63 μ mHe-Ne激光器中,均匀展宽起着重要的作用。
The expression for inversion density in a gas laser includes an additional term if one allows elastic and/or resonant collisions among the active atoms. This term is a function of the line parametersγ1, andγ2 and describes the effect of homogeneous broadening on the saturated gain profile. Measurements of these parameters show that the homogeneous broadening in a 0.63 μm He-Ne laser plays an important role.
