A technique of direct femtosecond laser-induced crystallization of glass enhancing homogeneity of continuous crystalline tracks formed in lanthanum borogermanate glass using a beam with the waist cross section of an elliptical form instead of a conventional circular one was proposed. Obtained crystalline tracks give evidence of the waveguiding effect and the frequency conversion ability.
