Pulse laser generation in several Er3+,Yb3+:glasses thermally bonded with Co2+:MgAl2O4 was achieved. Peak power in the range of 1.83-7.68 kW with pulse duration between 2.9 and 4.2 ns and energy up to 24 mu J was obtained. The output characteristics for different transmissions of the output couplers were investigated. To show the improvements gained by the thermal bonding procedure, a comparison of thermally bonded and unbonded samples was done in terms of generation efficiency, peak power, beam quality, generated spectra and pulse to pulse jitter.
