Strong optical scattering by femtosecond laser induced microbubbles inside water and other microscopic observations / Sayed Ahmed Islam Sanny

Nonlinear interactions of focused femtosecond laser with water can provide interesting optical phenomena, most commonly, laser induced breakdown in water which creates plasma, self-focusing or filamentation because of loose geometrical focusing condition, white light generation and blue shifted by p...
