Why this Happens
when the inexpensive laser is presented to you out of the box, its not used to its full potential. The laser diode on hte inside has much more power than we know to unleash. By twisting the potentiometer, the laser diode goes from 52nm to 45nm. This makes the laser thinner, smaller, and most importantly, stronger and more powerful!
