Double reducing threshold of laser oscillation between two crystals of equal geometry (3x3x10 mm3) and different pump absorption (80 and 50 %, correspondingly) was observed. For both cases the value of slope efficiency was nearly 22%. The lowest threshold of absorbed pump power 360 mW with 2% OC was measured for series crystals with small pump absorption. The focusing of pump beam was no tight (waist radius 38 mm) in comparison with similar experiments with forsterite crystals.
