On limitation of the pulse repetition rate in copper vapour laser associated with prepulse electron density

Limitations imposed on the pulse repetition rate due to the presence of the prepulse electron density are considered. The existence of the critical prepulse electron density formulated by S. I. Yakovlenko [Quantum Electron. v. 30, No. 6, p. 501 (2000)] is analysed. It is shown that the approach adopted in this paper does not prove the existence of critical density.
