Theory of femtosecond strong field ion excitation and subsequent lasing in N
Vladimir T. Tikhonchuk, Yi Liu, Rostyslav Danylo +2
Delayed cavity-free forward lasing at the wavelengths of 391 and 428 nm was observed in recent experiments in air or pure nitrogen pumped with an intense femtosecond laser pulse at…

Lasing without population inversion in air
André Mysyrowicz, Rostyslav Danylo, Pengji Ding +8
A cavity-free laser in the sky could lead to revolutionary improvements in optical remote sensing for atmospheric science. Abundant in air, nitrogen molecules are prime candidates…
