All of the sticky posts and links in the Lasers forum seem to be a decade old. Are there current answers to the following FAQs?
- How can I measure laser output power? (Last answer in stickies: "Go to a local university!")
- How can I check for IR output on a laser? (And if it's leaking IR, how can I filter it?)
- What sort of duty cycle can I expect for a given power output level and heat sink capacity?
- What should I expect to pay for a stable output at various power levels, and what are reputable sources for Class-4 kits?
- What specs should I look for in eye protection, what should I expect to pay for Class-4 protection, and what are reputable sources for said safety glasses?
