Generation of Rotational Raman Emissions and Self-compressed Femtosecond Pulses in a Hydrogen GasWe observed the characteristics of a femtosecond laser pulse after passing the beam through a hydrogen gas. The pulse compression accompanied by Stokes emissions implies the coherently spectral broadening based on a Raman rotational coherence.

Hematopoietic Stem Cells in Vascular Development and Ocular NeovascularizationNeovascular diseases of the eye include retinopathy of prematurity (ROP), proliferative diabetic retinopathy (PDR), and the exudative or “wet” form of age-related macular degeneration (ARMD). Together these diseases affect all age groups and are the leading causes of vision impairment in developed nations [.].

Spectral-temporal soliton dynamics analysis near second zero-dispersion point in photonic crystal fiThe propagation dynamics of an ultrashort optical pulse near the second zero-dispersion point of a small-core high-delta photonic crystal fiber is investigated using cross-correlation frequency-resolved optical gating. Negative dispersion slope strongly influences the observed behavior.

c-wave of ERG in carriers of Leber congenital amaurosisLeber’s congenital amaurosis is a congenital retinal dystrophy characterized by profound visual loss from birth, coarse nystagmus, extinct ERG and the appearance of degenerative and pigmentary changes from the fundus. In a high proportion of the presented cases there is history of parental consanguineous marriage.

Microstructured fiber feedback pulse compression to few optical cyclesA feedback system that combined modified-SPIDER and 4-. active-chirp compensation enabled us to compress photonic-crystal-fiber and tapered-fiber outputs to 6.6 and 8.4 fs, respectively. Compressed-pulse results well agree with fringe-resolved autocorrelation measurement ones.
