Because short pulse Nd:YAG laser of nanosecond pulse-width and high peak power has a unique capability to improve the mechanical properties of metal parts, a study on the development of high peak power short pulse from Nd:YAG laser along with its peening application has been performed. The design scheme of laser and the characteristic of laser beam transmission are presented and discussed. A pulse energy of 25 J with 15 ns pulse-width and a maximum peak power of 1660 kW laser system which use one oscillation and eight amplifiers has been achieved. Laser beam has a max divergence angle of 0.03 mrad, a pulse-to-pulse pulse-width stability of ±0.1 ns, and the pulse-to-pulse energy stability factors of less than ±2.8%. A low value of divergence means an easier modification of a nearly hat-top laser beam intensity profile and an easier transmission of laser beam. To evaluate the performance of the laser system, several metal materials are processed. Laser peening quality and efficiency are analyzed by using an optical microscope, a transmission electron microscope, and an X-ray diffraction device. The processing results show that the performance of this laser system is excellent.YAG laser, laser beam, peak power, laser peening Citation:Qiao H C, Zhao J B, Yang H.

The course Laser Principle and Technology for undergraduates is a multi-physics subject with main contents of laser's basic principle, laser modulation techniques, Q-switching techniques, etc. . In order to help students understand the complex theory and to integrate the theory with the engineering practice, we developed a virtual simulation platform/software. This platform consists of three main modules (laser generation, laser propagation and laser controlling), which can be subdivided into eight secondary modules, including laser output characteristics, laser resonator, laser modulation, frequency conversion, et al. . Each module has its input and output parameters and can be modified by the user. The theoretical models and the algorithms are introduced in this article. The output characteristics of the relaxation oscillation process are presented as an example of the simulation results.
