Integrated pulse scope for tunable generation and intrinsic characterization of structured femtosecond laser

Abstract Numerous techniques have been demonstrated for effective generation of orbital angular momentum-carrying radiation, but intracavity generation of continuously tunable pulses in the femtosecond regime remains challenging. Even if such a creation was realized, the generated pulses—like all pu...
