MUS had the fastest tissue dissolution rate (P < 0.01), at 2.986% ± 0.395% per second. The laser systems had dissolution rates of 0.388% ± 0.062% per second for Er:YAG laser, 0.316% ± 0.042% for Er,Cr:YSGG laser A, and 0.258% ± 0.018% for Er,Cr:YSGG laser

The development of an ultra-high spectrum purity laser from a weak external distributed perturbation is covered in a recent article from Opto-Electronic Advances.
