It is defined as the time required for the photodetector output signal to change from 10% to 90% of the peak level. A good rule of thumb is to choose a photodiode with a rise time that is one fifth of the laser pulse width to be measured.
WebAug 9, 2024 · The pulse-burst laser can output 2.3 J/pulse at 1064 nm or 1.3 J/pulse at 532 nm, with a repetition rate of 10 kHz and a burst duration of 10 ms. To avoid optical breakdown in weakly ionized plasmas, the laser pulse was stretched to a duration of ∼70 ns to maintain a similar pulse energy but lower the intensity. Webwhere ω n = (E n - E' 0) / ℏ is the Bohr frequency.In the limit of an ultrashort pulse, the lifetime (τ) of the process under laser excitation approaches zero and α n = C < φ n χ 0 >. Hence, ψ = C φ n = χ 0.Accordingly, …
