Strontium vapour laser with a pulse repetition rate of up to 1 MHz
For the first time it has been shown that the pulse repetition rate of the lasers on the self-terminating transitions of metal atoms may be as high as {approx}1 MHz. The highest pulse repetition rate equal to {approx}830 kHz was realised on self-terminating IR transitions in Sr I atoms ({lambda} = 6.456 {mu}m and {approx}3 {mu}m) and in Sr II ions ({lambda} {approx} 1 {mu}m) in a strontium vapour laser operating in a self-heating pulse periodic regime. The energy yield of a Sr laser was found to be proportional to the energy input into the active medium in a wide range of excitation pulse repetition frequencies; in this case, the average total specific output laser power is equal to 30 - 40 mW cm{sup -3}.
