Abstract
The optimum photon lifetime for the minimum pulsewidth of a gain-switched laser is investigated both analytically and numerically. For a fixed pump power, the shortest pulse can be produced when the laser cavity is optimized to give an optical pulsewidth that is /spl sim/2.5 times the photon lifetime. This is in good agreement with experimental results.<>
