"pulses create durable patterns of tellurium and tellurium-oxide crystals, forming at exact point where laser meets glass... after etching simple line pattern onto 1-cm-diameter section of tellurite glass, can generate current under UV and visible light... capability maintained reliably for months... also, sensors...windows and other glass structures"
