Photonic crystal fibre enables short-wavelength two-photon laser scanning fluorescence microscopy with fura-2

Phys Med Biol. 2004 Oct 21;49(20):4757-63. doi: 10.1088/0031-9155/49/20/007.

Abstract

We report on a novel and compact reliable laser source capable of short-wavelength two-photon laser scanning fluorescence microscopy based on soliton self-frequency shift effects in photonic crystal fibre. We demonstrate the function of the system by performing two-photon microscopy of smooth muscle cells and cardiac myocytes from the rat pulmonary vein and Chinese hamster ovary cells loaded with the fluorescent calcium indicator fura-2/AM.
