Laser‐beam attenuation for spatial profiling of small focal spots

Laser‐beam attenuation for spatial profiling of small focal spots

We describe an attenuation scheme for high‐power laser beams which uses only two optical surfaces and is continuously variable over several orders of magnitude. We demonstrate its application to the spatial profiling of a pulsed DF laser focal spot with 10−2 cm diameter and ≳1010 W/cm2 peak irradian...

Zusammenfassung:We describe an attenuation scheme for high‐power laser beams which uses only two optical surfaces and is continuously variable over several orders of magnitude. We demonstrate its application to the spatial profiling of a pulsed DF laser focal spot with 10−2 cm diameter and ≳1010 W/cm2 peak irradiance.
