8. How do mirrors for most lasers achieve high (>95%) reflectivity not possible with simple metal coatings alone? Describe the structure of these mirrors (include a diagram showing the "stack" of multiple layers used) and describe, in a paragraph, how dielectric mirrors (also called "dichroic" mirrors) work. Be sure to detail the principles of operation, the thickness of the layers, and why that thickness is a critical parameter.
