通过测量作为输出镜反射率的函数的激光阈值，确定了Nb：YVO 4中1064（4F 3/2 → 4 I11/2）和1342 nm（4F 3/2→ 4 I13/2）处的受激发射截面。小样本Nd：YVO 4和Nd：YAG在室温下用cw 514.5-nm氩离子激光器以几乎相同的几何布置进行端面泵浦，这允许获得比较值。假设Nd：YVO的泵浦量子效率与Nd：YAG相似，则1064和1342 nm跃迁的受激发射截面分别为12×10−19和6.0×10−19 cm 2。
The stimulated‐emission cross sections at 1064 (4F3/2→4I11/2) and 1342 nm (4F3/2→4I13/2) in Nb : YVO4 were determined by measurement of laser thresholds as a function of output mirror reflectivity. Small samples of Nd : YVO4 and Nd : YAG were end pumped at room temperature with a cw 514.5‐nm argon ion laser in an almost identical geometrical arrangement which permitted comparative values to be obtained. Assuming that the pumping quantum efficiency of Nd : YVO is similar to that of Nd : YAG, the stimulated‐emission cross sections obtained for the 1064‐ and 1342‐nm transitions were respectively 12×10−19 and 6.0×10−19 cm2.
