Blazing dual-sun
Blazing dual-sun generated in the femtosecond beam path. The scattering of excitation femtosecond pulses incident at the focal lens causes the below “sun”. Meanwhile, the transmitting light of ionized femtosecond laser pulses shined on a piece of white paper forms the blazing “sun” sits atop. Olympus C5050Z.
