Problems solved by technology

However, laser crystals based on YSGG and GSGG also have some disadvantages. For example, some dopant ions such as Nd ions have a small segregation coefficient in YSGG, which makes it relatively difficult to grow laser crystals with uniform optical quality. At the same time, in some special applications field, the output wavelength of rare earth activated ions based on YSGG and GSGG is difficult to meet the application requirements, and GSGG is easy to crack during growth, and there is a large growth core
