Tunable second harmonic generation by phase-modulated ultrashort laser pulses
(SPRINGERNEW YORK, 2012)
We report on the generation of tunable light around 400 nm by frequency-doubling ultrashort laser pulses whose spectral phase is modulated by a sum of sinusoidal functions. The linewidth of the ultraviolet band produced ...
Tunable random lasing in dye-doped mesoporous silica SBA-15
(2021-02-01)
Mesoporous silica, known as SBA-15, possesses a hexagonal pore structure, with 8-nm-diameter pores and high surface area (∼700m2/g). The mesoporosity of SBA-15 is excellent to be filled with luminescent chromophores aiming ...
Erbium ring fiber laser cavity based on tip modal interferometer and its tunable multi-wavelength response for refractive index and temperature
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-08-10)
A tunable multi-wavelength fiber laser is proposed and demonstrated based on two main elements: an erbium-doped fiber ring cavity and compact intermodal fiber structure. The modal fiber interferometer is fabricated using ...
