The strongest pumping bands is a four level system of Nd: YAG laser at wavelength of range_________________ Correct Answer 0.75 and 0.81 nm

The Nd: YAG laser is a four level system. It consists of number of pumping bands and fluorescent transitions. The strongest pumping bands are the wavelengths of 0.75μm and 0.81μm. and gives lasing transition at 1.064μm and 1.32μm. Single mode emission is usually obtained at these wavelengths.
