Question

How are reflecting telescopes similar to devices that produce laser light?

Both use crystals to produce a beam of light. 
Both have convex lenses that magnify objects.  
Both have concave lenses that magnify objects. 
Both use mirrors to reflect a beam of light.

GPT-5 mini · Answer

Both use mirrors to reflect a beam of light.

Reflecting telescopes use mirrors (a primary concave mirror and often a secondary) to collect and focus light. Laser devices use mirrors in their optical cavity to reflect light back and forth through the gain medium, amplifying it; one mirror is partially transmissive to let the laser beam out.
