Letting go lasers
2015/7/13
Small objects tend to cling to everything. It's why parents dread hosting parties that involve confetti. It's why glitter is fun for crafts--until it finds its way onto everything else you touch.When ...
Highly Tm-doped silicate glasses and fibers were developed, which exhibit a high slope efficiency of 68.3% and a gain per unit length of greater than 2dB/cm. Single frequency fiber lasers with laser l...
