Abstract

In this work, different thermal lens focal lengths with different pumping repetition rates for ceramic and single crystal Yb:YAGare calculated for controlling the thermal focal length without using additional optical elements . The effect of pumping energy and pump beam diameter on the thermal focal length is studied. Finally, the stability of the cavity is investigated via ABCD matrix method.
