The influence of the cavity trapped amplified luminescence (CTAL) on the threshold, power and dynamic characteristics of Er, Yb : glass lasers with end and side diode pump configurations has been studied. The CTAL loss coefficient has been evaluated using the luminescence balance equation. The inverse proportion dependence of the CTAL loss coefficient on the cavity length has been revealed. It has been shown that amplification of luminescence in the laser cavity leads to a significant increase of the threshold pump power (∼3-5 times). The Er, Yb : glass laser generation dynamics has been modelled taking into account the luminescence evolution beginning with the onset of the diode pumping pulse. Depending on the diode pumping pulse amplitude, the increase or decrease of the Er, Yb : glass laser pulse generation delay can be observed.
