Spatial beam self-cleaning in multimode lanthanum aluminum silicate glass fiber [PDF]
R. Gu\'enard et al., Spatial beam self-cleaning in multimode
lanthanum aluminum silicate glass fiber, Optical Fiber Technology, v.53,
102014, 2019, 2019 We demonstrated that spatial Kerr beam self-cleaning can be obtained in a highly multimode multicomponent optical fiber based on lanthanum aluminum silicate oxide glasses (SiO2-Al2O3-La2O3), which was made by using the modified powder in tube technology (MIPT).
