    Area of Science:

    • Laser Physics
    • Optics
    • Photonics

    Background:

    • Recent advances in producing structured light fields using custom laser cavities.
    • Lack of a universal method for designing laser cavities for arbitrary structured light fields at both ends.

    Purpose of the Study:

    • To outline a general design approach for generating structured light from lasers.
    • To enable specification of laser cavities for desired structured light fields at both the output and gain ends.

    Main Methods:

    • Numerical simulations to verify the design approach.
    • Experimental validation using an unwrapped cavity setup.

    Main Results:

    • A general design approach for laser cavities producing structured light was developed.
    • The approach allows for maximizing pump overlap for higher power.
    • Minimization of thermal effects for improved brightness was achieved.

    Conclusions:

    • The presented design approach offers a universal method for laser cavity design.
    • It facilitates the creation of desired structured light fields, even if different from the gain-end profile.
    • This work is valuable for laser communities seeking high brightness and customized output beams.
