Due to an unfortunate oversight this paper was published with typographical errors in Keywords and Eq. (5).


In keywords, Yb · YAG should be changed to one keyword, Yb:YAG.


In Eq. (5), \(hv_{L}\) should be changed to 1 as follows:

$$\frac{{\phi_{{{\text{ASE}}}} }}{{t_{r} }} = \frac{\Omega }{{4\, \cdot \,t_{r} \, \cdot \,c}}\, \cdot \,\frac{1}{{\tau_{g} \sigma_{g} }}\, \cdot \,\frac{{G_{0} }}{{(\ln G_{0} )^{1/2} }}.$$
