Abstract
This paper summarizes the physics and experimental results pertaining saturable absorbers based on Cr4+ doped crystals, in several types of diode-pumped Nd and Yb - doped solid state lasers. The paper focuses on the understanding and on analyzing the saturation curves of several Cr4+ garnets and other crystals (such as forsterite). Several systems of passively Q-switched diode-pumped lasers and microlasers were also described, and their performance in terms of average output power, pulsewidth and repetition rates were described and analyzed. Analytical models which use some measured physical constants were used to predict the Q-switched laser performance.
