KTP BBO YVO4  
Neodymium Doped YttriumOrthvanadate(Nd:YVO4)

Advantages:

High absorption over  a wide pumping wavelength bandwidth 
Large stimulated emission  cross-section at lasing wavelength  
Lower lasing threshold  and higher slope efficiency 
Low dependency on pumping  wavelength and tend to single mode output  
Optically uniaxial and  large birefringence grant strongly-polarized laser emission
