Detection of radiation from a Ti:sapphire laser with a high space – time resolution

A high space – time resolution is achieved in detection of radiation from a Ti:sapphire laser by the methods of femtosecond photoelectronics. A time resolution of 2 × 10^-13 s is obtained at wavelength of 800 nm in a linear scan regime for a streak speed of 5 × 10¹⁰ cm s^-1, an input power density of (1 – 5) × 10³ W cm^-2, and a linear dynamic detection range no more than 10.
