Ophthalmic ultrahigh resolution OCT using a portable low cost Ti:Al_2O_3 laser

摘要

A compact, low cost prismless Titanium:sapphire laser with 154nm bandwidth and 20mW output power was developed and ultrahigh resolution OCT ex vivo imaging in an animal model with sub-2μm and in vivo imaging in patients with 3μm axial resolution is demonstrated. This light source not only significantly reduces costs for broadband OCT light sources, but has also great potential for clinical OCT applications due to its small footprint (500 * 200 mm including pump laser), user-friendliness and power stability.
