Through the partial substitution of Y 3+ ions with La 3+ ions in the structural framework of YCa 4 O(BO 3 ) 3 , the Yb 3+ ‐doped mixed oxyborate Y 1− x La x Ca 4 O(BO 3 ) 3 ( x = 0.09 and 0.25) crystals have been grown and characterized. The La 3+ content ( x = 0.25) in the crystal far exceeds the La 3+ doping limit ( x = 0.1) previously reported, whereas the crystal remains transparent and free from cracks. Optical absorption, emission and fluorescence decay measurements have been performed at room temperature, and the influence of La 3+ doping on the spectroscopic characteristics of the crystals has been presented and discussed in detail. The main spectral and laser parameters pertinent to laser potential have been evaluated and compared with those of other oxyborates. The perspectives for application of the Yb 3+ :Y 1− x La x Ca 4 O(BO 3 ) 3 crystals as laser media have been discussed.
