Homework Statement

Hi. Somebody can aswer or at least help me in aswer the follonwing question? In a Q-Swtched CO2 laser system, which is the optimal time interval to maximize the pulse peak power? Becasue in some literature it says that if the time of low Q (high losses) is larger than the CO2 (001) vibrational laser level lifetime, the population invertion is depleted by spontanoues emission and if it shorter than the 001 lifetime the population inversion can not achieve the maximun value. However, in other literature it is reported that the low Q value should be of the order of the 0110 laser lower auxiliar level lifetime. Sombody has clear this issue? I refer to the optimal interval time of the cavity obturation with a chopper or other intracavity element.

Your post has a section labeled "relevant equations", but it has been left blank. Did you mean to fill that section out before posting?

To comment on the statement "in other literature it is reported that the low Q value should be of the order of the 0110 laser lower auxiliar level lifetime". The consensus is more so that the ideal condition is found when low Q time < the 0110 lifetime. This minimizes depletion of the lower axillary level and maximizes gain.
