The laser generation was produced at a wavelength of 1562.4 nm with a small spectral bandwidth of 0.4 nm using a short-pulse erbium doped fibre laser with unique group delay dispersion. This process was generated by Q-switching, which was accomplished using a vanadium oxide polyethylene glycol (V2O5-PEG) film saturable absorber (SA) within an all-fiber ring cavity arrangement. The laser generated a peak output power of 0.4 mW, a maximum pulse energy of 3.2 nJ, and an astonishingly brief pulse width of 4.7 s. These results highlight the possibility of the V2O5 film as a workable SA substitute for producing pulsed lasers.

Generowanie lasera zostało wytworzone przy długości fali 1562,4 nm z małą szerokością pasma widmowego 0,4 nm przy użyciu krótkoimpulsowego lasera światłowodowego domieszkowanego erbem z unikalną dyspersją opóźnienia grupowego. Proces ten został wygenerowany przez przełączanie Q, które zostało osiągnięte przy użyciu nasycalnego absorbera (SA) z tlenku wanadu, glikolu polietylenowego (V2O5-PEG) w układzie wnęki pierścieniowej z wszystkich włókien. Laser generował szczytową moc wyjściową 0,4 mW, maksymalną energię impulsu 3,2 nJ i zdumiewająco krótką szerokość impulsu 4,7 s. Wyniki te podkreślają możliwość zastosowania folii V2O5 jako wykonalnego substytutu SA do produkcji laserów pulsacyjnych.
