850, 905, 1064 and 1535 nm behave differently in detector choice, optics and eye safety. What the label hides, and the four questions to ask a supplier.
The three measurements that decide whether a returned unit is out of spec, the instrument traps in each, and what an acceptance record has to contain.
Raw divergence is set by the emitting aperture. What a beam expander can and cannot buy, why clipping ruins it, and how alignment error scales with magnification.

Why pulse energy density rather than total energy sets coating life, what the published ERDI shot counts mean in operating hours, and how to keep a source at its rated life.
Where heat is generated in a pulsed 1535 nm source, what the published temperature range assumes, and how continuous versus burst duty cycle changes the thermal budget.
What an Er:Yb glass pump driver has to deliver, why the drive pulse is a ceiling, the charge arithmetic behind the supply, and how ground return and trigger timing spoil results.
How pulse energy, drive current, thermal load, divergence, lifetime and mass scale across the ERDI 1535 nm source range, with all 16 models side by side.
