WebCrystal Cave is an excellent example of a marble cavern. A half-mile loop trail leads through the cave, and there's also a steep half-mile walk to and from the cave parking area to the entrance. Because of fragile formations, the only way to visit the cave is on a guided tour. Tours are suitable for all ages. WebIn principle, even a strong thermal lens could be compensated by adjustments of the design of the used laser resonator – for example, with a convex (defocusing) laser mirror next to the laser crystal. Nevertheless, thermal lensing …
