采用熔盐法获得了Yb3+和Er3+离子掺杂浓度分别为25和1.1at.%的YAl3(BO3)4晶体。利用970nm半导体激光器作为泵浦源,通过调节其准连续运转的占空比实现了增益介质在不同晶体温度下的激光运转,并分析了不同Er:Yb:YAl3(BO3)4晶体温度对1.5μm波段输出波长的影响。在端面泵浦的平-凹腔中,分别实现了1600、1550、1540、1520nm4种波长的激光运转,其斜率效率分别为21%、6%、17%、15%。当吸收泵浦功率为15.7W时,这4种激光波长的最大准连续输出功率分别达到2.4,0.64,1.5和1.2W。这种输出波长的温度效应有可能成为一种获取1.5μm波段特定应用波长激光的方法。 YAl3 (BO3) 4 crystals with Yb3 + and Er3 + doping concentrations of 25 and 1.1 at%, respectively, were obtained by the molten salt method. By using a 970nm diode laser as a pump source, the laser operating at different crystal temperatures was achieved by adjusting the duty ratio of quasi-continuous operation. The effects of different Er: Yb: YAl3 (BO3) Effect of wavelength output wavelength. In the end-pumped flat-cavity, the laser operating at four wavelengths of 1600, 1550, 1540 and 1520 nm respectively is achieved with slope efficiencies of 21%, 6%, 17% and 15% respectively. When the absorption pump power is 15.7W, the maximum quasi-continuous output power of the four laser wavelengths reaches 2.4, 0.64, 1.5 and 1.2W respectively. The temperature effect of this output wavelength has the potential to become a means of obtaining a laser of a specific application wavelength in the 1.5 μm band.
