Description

428 nm forward lasing action was observed from a femtosecond laser filament in air created by Ti:sapphire laser pulses. The 800 nm femtosecond laser filament not only provides a source for population inversion between two vibrational levels (B2Σu+(0) and X2Σg+(1)) of N2+ but also generates a 428 nm seed from filament-induced white light. This simple technique will find more applications in standoff spectroscopy. (letter)
