Specifications
ER4000 is part of the 1535 nm erbium-glass pulsed laser family. Its current PDF lists pulse energy ≥4 mJ and optical pulse width 12 ns. Repetition-rate status is shown separately in the table. These are the source's distinct specifications; none establishes the distance or accuracy of a finished instrument.

Source-version clarification
Repetition rate: the current PDF table gives 1–5 Hz; its introduction gives 1–10 Hz. The table entry is displayed; the ordered repetition-rate rating is pending confirmation.
Reading this model's optical specifications
The recorded raw beam diameter is 0.5 mm and divergence is ≤ 4mrad. The current specification table does not state the divergence's full-angle/half-angle convention or the beam-width measurement method. Those definitions remain unspecified until a beam report confirms them. The beam-mode entry does not, by itself, supply a measured M² value.
Values above were checked against the current model PDF, including its inequality signs and stated measurement qualifiers. Source entries of “Class 1” require the corresponding classification report; shock, vibration and lifetime entries likewise need their stated test conditions. Missing tolerances and statistics are not reconstructed from another model or a paper.
