In this paper a new threshold theory of laser is given and analytical formula of the theory is introduced. The threshold values for some kinds of lasers are discussed. The relationship between the threshold inversion and the oscillating duration is investigated experimentally. And the measured result is in good agreement with that of the new threshold theory of laser.
