Abstract:In this paper we report the results of the research on a double side-pumped Er:Yb:glass slab laser. Due to the nonsymmetric power distribution inside the slab a displacement of the laser beam is observed thus leading to cavity misalignment and consequently to extraction efficiency loss. At repetition rates of about 5Hz this allows just a burst operation with an increased thermal load inside the slab. Numerical-theoretical studies about time-dependent temperature distribution in the laser material with appropri… Show more
