Passive Q-switching of diode-pumped laser

A laser system, comprised of: a laser cavity; a gain medium a pump, a saturable absorber (SA); a first mirror and a second mirror; wherein a ratio of an area of the beam area within the SA to an area of the laser beam within the gain medium is greater than 1, and wherein the beam generates a gain me...

Summary:A laser system, comprised of: a laser cavity; a gain medium a pump, a saturable absorber (SA); a first mirror and a second mirror; wherein a ratio of an area of the beam area within the SA to an area of the laser beam within the gain medium is greater than 1, and wherein the beam generates a gain medium radius spot on the gain medium and a saturable absorber radius spot on the saturable absorber such that a ratio between a saturable absorber radius spot on the saturable absorber and the gain medium radius spot on the gain medium is within a range of 1.7-7 is disclosed. A method for using the laser system e.g., for producing a pulsed energy is further disclosed.
