Highlights
Full-bandwidth spectral transfer
of truncated ultrashort-pulse Bessel beams through a diaphragm in self-apodization
setup:
Spatio-spectral
maps for a 10-fs Bessel beam before and after self-apodizing
truncation
(i.e. the perimeter of diaphragm
matches the first minimum of Bessel distribution), left: axial distance
from diaphragm z = 0 cm, right: z = 13
Opt. Expr. 16, 1077-1089 (2008)
Self-reconstruction of femtosecond
Bessel beams:
X-waves in space and time, low-dispersion hybrid refractive-reflective beam shapers)
Self-reconstruction of a significantly
disturbed ultrashort-pulse Bessel beam during free-space propagation
at different distances:
(a) 2.9 mm, (b) 4 mm, (c) 6 mm, (d) 7 mm, (e) 8 mm, (f) 9 mm,
compared with (g) 9 mm without disturbance
(time-integrated, field of view 329 x 320 µm2,
disturbing object: 30 µm gold wire at 2.9 mm distance, Ti:sapphire
laser, pulse duration
12 fs). Radial Bessel structure as well as spatio-temporal X-pulse
structure information can be reconstructed.
