Specifications
ER900 is part of the 1535 nm erbium-glass pulsed laser family. Its current PDF lists pulse energy ≥900 μJ and optical pulse width 7 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
Storage temperature: the current PDF table gives −55 to +75°C; its introduction gives −55 to +85°C. The table is displayed, but this individual limit is pending confirmation for the ordered version.
Reading this model's optical specifications
The recorded raw beam diameter is 0.3 mm and divergence is ≤ 7 mrad. 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.
