Nd-doped silicate glass is a kind of laser glass with neodymium as active ion and silicate glass as the base body. It has larger stimulated emission cross section and wider effective fluorescence line width. Also, it has good laser performance and gain performance. It can be widely used in the manufacture of lasers. This wider line of glass and the availability of narrower ultrashort pulses make it the first choice for lasers with high energy and high peak power.
