| 摘 要： | 本文报道了我所生长的大尺寸硼酸铝钕晶体的脉冲激光特性。当用氙闪光灯泵浦时,φ3.2mm×23.7mm的NAB激光棒,最大激光输出为每个脉冲422mJ。对于φ1.8mm×2.4mm的激光棒,激光阈值为67mJ。激光输出为线性偏振光,波长1.063μm。用BDN染料片调Q时,φ1.2mm×8.4mm的NAB棒激光单脉冲宽度为8ns,光束发散度为2mrad。

Pulsed laser characteristics of neodymium aluminum borate [NdAl3(BO3)4] (NAB) crystals |

| Abstract: | This paper presents the pulsed laser eharateristics of laser NAB crystals grown in our institute. The maximum laser outpu t of a NAB rod with dimensions of 3. 2mm X 23. 7mm was 422mJ a pulse when it was pumped with a single xenon flashlamp. The laser threshold of a NAB crystal rod with dimensions of 1.8mmX 2.4mm was determined to be 67mJ. By using BDN dye for switching, the laser pulse width of a NAB rod with dimensions of 1.8minx8.4 mm was 8ns. The output laser beam was linearly polarized with beam divergence angle of about 2mrad and wavelength of A=1.063 μm. |
