Tantalum aluminum carbide () phase ceramic (MAX) material has attracted much attention because of its high conductivity, high strength, corrosion resistance, and good optical properties. However, there are too few reports on lasers with -based saturable absorbers (SAs). We prepared and characterized a -based SA whose nonlinear absorption performances were achieved at a 2 µm waveband range and which was used in a passively -switched (PQS) Tm:YAP laser. In the PQS mode, a maximum average output power of 0.78 W was achieved with the central output wavelength of 1991.86 nm from a PQS Tm:YAP laser, corresponding to a pulse duration of 926 ns at 143.8 kHz.
钽铝碳化物（）相陶瓷（MAX）材料因其高导电性、高强度、耐腐蚀性和良好的光学性能而备受关注。然而，关于基于的可饱和吸收体（SA）的激光器的报道却很少。我们制备并表征了一种基于的SA，其非线性吸收性能在2μm波段范围内实现，并用于被动调Q（PQS）Tm:YAP激光器。在PQS模式下，PQS Tm:YAP激光器的中心输出波长为1991.86nm，最大平均输出功率为0.78W，对应于143.8kHz时926ns的脉冲持续时间。
