Estimate the longitudinal mode number q
WebDec 31, 1996 · This paper provides a mathematical analysis to calculate the number of longitudinal modes and their relative strength in a dye Q-switched ruby laser. The calculations were based on formulae developed to accurately predict the number of loop transits that occur while the laser pulse builds up from noise levels.

All physical problems must have an answer that is a real number. Complex numbers have no physical meaning. 2. Complex numbers are a convenient mathematical method for handling trigonometric functions. In the solution of a physical problem, complex numbers can always be grouped to form real numbers. 3.
