Abstract : A general method for designing a laser system is presented. Using the Ti:sapphire laser as an example, the requirements of stability, astigmatic compensation, and matching of the pump and cavity modes are addressed. Investigations into the relaxation oscillations of a Ti-sapphire laser are reported. Using four level laser rate equation theory, a technique is developed for analyzing relaxation oscillations exhibited by a laser. This technique presents a new and simple method for measuring the upper state lifetime and intrinsic cavity losses of a laser system. Beam-like vector solutions to Maxwell's equations are also presented. These solutions present a more detailed description of the polarization properties of laser beams. Experimental evidence of these properties is shown using an Argon laser.
