The art of femtosecond laser writing [PDF]
Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009 Common beliefs that laser writing does not change when reversing beam scan or propagation direction are challenged. Recently discovered phenomena of quill and non-reciprocal femtosecond laser writing in glasses and crystals are ...
