| Abstract: | The shift coefficient of the central wavelength of diode laser under different operating current was measured.The gain distrubution in the Nd:YAG rod was theoretically studied using ray tracing program.Without the help of collimating lens,a high efficiency diode-side-pumped module was designed with maximam output power of 218W.The maximum optical-optical efficiency is 37% and the electrical-optical efficiency is about 18.5%. |
