More Information
Summary:Method and system for laser crystal degradation compensation are disclosed. The method includes: defining a plurality of sites on a frequency converting crystal; determining a degradation rate associated with each of the plurality of sites; determining an amount of time T wherein a site is continuously operable within a tolerated variation of at least one beam parameter, the amount of time T being determined based on the tolerated variation of the at least one beam parameter and the degradation rate; determining an amount of time t wherein t is a fraction of T; and iteratively shifting among the plurality of sites, wherein each of the plurality of sites is utilized continuously for a duration of time t for each iteration.
