Laser specifications decoded

Linewidth, spectral width, RIN, M², and coherence length answer five different questions. Translate each into the units your experiment is designed in — and learn which ones not to pay for.

Fiber polarization control

Single-mode fiber does not preserve polarization. Pin the state, erase it with a scrambler, or maintain it in PM fiber — which one your measurement needs, and the response time and extinction ratio that decide it.
