Controlled visible ultrafast lasers based on polarization-dependent photonic devices

The realization of controlled modulation of ultrashort pulses in the all-solid-state visible ultrafast lasers is a challenge, limited by the development of advanced optical modulation devices. Here, we reported a Ta2PdSe6 photonic device-based controlled visible ultrafast laser that exploits the polarization-dependent optical response of the Ta2PdSe6 photonic device to modulate the pulse width. Ultrashort pulse widths of 33.3 ps and 36.6 ps can be achieved under the horizontal and vertical polarization emission, respectively. This study presents polarization-dependent photonic devices for solid-state lasers, which might lead to the creation of controlled modulation in visible ultrafast lasers.
