We densify dilute plasma in femtosecond laser filaments by heating it with energetic 200 picosecond-long laser pulses. Differently from the case of nanosecond heating, the densified plasma channels, under certain conditions, remain smooth and continu

• Background: In vivo retinal injury studies using ultrashort-pulse lasers at visible wavelengths for both rabbit and primate eyes have shown that the degree of injury to the retina is not proportional to the pulse energy, especially at suprathresh
