In the evolutionary pathway toward the fiber laser, what step occurred immediately after Elias Snitzer developed the low-loss waveguide foundation in the Early 1960s?
Answer
Doping of these fibers with rare-earth elements, leading to the first fiber laser demonstrations
The stated pathway shows that following Snitzer's creation of the foundation in the early 1960s, the next step involved adding rare-earth dopants to make the fiber active.
