In dental health care, the application of ultrashort laser pulses enables dental tissue ablation free from thermal side effects, such as melting and cracking. However, these laser types create undesired micro- and nanoparticles, which might cause a h

Due to the high absorption coefficient of water in biological tissues at 3 micrometer, the Er:YAG (2.94 micrometer) and the Er:YSGG laser (2.79 micrometer) are very effective tools for medical applications. A widespread use of these lasers is prevent
Liquid-core fused silica capillary lightguides for applications in the UV/VIS and NIR spectral range

SPIE Proceedings.
Fused silica capillaries proved to be a suitable cladding material for liquid core lightguides. They have small diameters, a good mechanical stability and a high flexibility. Due to these properties such lightguides can be used for applications in mi
