We have analyzed the dynamics of the general V-shaped solid laser resonator in detail and pointed out its advantage and shortcoming. Its crucial shortcoming is the appearance of a high-loss region when the dynamics factor approaches 1ft≈1l1-f, and in this case the laser cannot run. In order to overcome this weakness, we have introduced a kind of improved V-shaped resonator proposed by Liu Jun-hai, and based on this we put forward an improved more compact V-shaped resonator.
