Overview

Experimental analysis demonstrates reduced contrast in two-photon fluorescence displays without complete mode locking, highlighting criteria to verify genuine picosecond pulses.

Key Points

To evaluate the validity and contrast limitations of two-photon fluorescence displays when characterizing picosecond pulses from mode-locked and non-mode-locked lasers.
Theoretically modeled two-photon fluorescence displays and contrast ratios under conditions of complete, incomplete, and absent laser mode locking.
Performed two-photon fluorescence measurements using dye Q-switched neodymium-doped glass lasers and a single-mode ruby laser to evaluate pulse formation.
Demonstrated that lasers lacking complete mode locking generate displays resembling picosecond pulse trains but exhibit reduced contrast ratios.
Confirmed picosecond pulse generation in dye Q-switched Nd:glass lasers through experimental two-photon fluorescence observations.
Observed contrast ratios in a single-mode ruby laser that matched predictions from the general correlation theory.
