Pump polarization effects in synchronously pumped mode-locked dye lasers

Abstract

Fast and continuous crosscorrelation measurements of a double synchronously pumped modelocked dye laser system Rev. Sci. Instrum. 55, 426 (1984);The effects of pump polarization on the performance of synchronously pumped mode-locked dye lasers have been investigated. A semiclassical model is derived and the numerical results are compared with experimental data. The theoretical pump polarization dependencies of the pulse shape, pulse width, peak power, and pulse delay have been determined, and experimental data obtained with an argon-pumped rhodamine 6G dye laser are in good agreement with the theory.

Dynamics of Ultrashort Pulse Generation and Amplification in Dye Lasers

“…coherence time represents a temporallag between the induced polarization and the electric field, coherence effects play an important role in limiting the magnitude and width of optical pulses [16,17,19,23,28,29]. However, when the optical pulse width is long compared to the coherence time, the rate equation approximation (or zero coherence time approximation 깐 = 0) is often used.…”

“…In order to have the highest interaction efficiency, th~~pump field needs to have the same polarization as the signal field, which was previously demonstrated in detail in a synchronously pumped mode-locked dye laser systems [28] . .…”
