In this work,we presented the measurements and calculations for the optimal pump conditions and their effects on thermal lens,fracture limit and laser efficiencies of end pumped Tm-doped yttrium aluminum perovskite(Tm:YAP)laser rod pumped at 1 064 nm.The results showed that the measured overall efficiency of produced laser at～1.98 pm is enhanced from 3.9％to 6.9％when the pump spot diameter is reduced from 390 pm to 210 pm.The maximum out-put power and oscillation threshold are also enhanced with reduced pump spot size.The maximum thermal stress and focal length of thermally induced lens are also addressed.
