Series-level technical context
Engineering context for a thin Multi-wavelength Lasers record
This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 11 nearby configurations on the same source-product record; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Typical operating fields in the series
- • Output / average power: 2.9 W
- • Output / average power: 11 W
- • Output / average power: 13 W
- • Power stability (rms, 4 hours±3℃): <2% , <1%
Beam-quality tolerance context
M², full-angle divergence and pointing stability are not present in this thin record. Treat all three as required order-confirmation fields because they determine focusability, propagation and alignment drift.
Optical integration schematic
- Step 1Laser head and temperature-stabilized base
- Step 2Safety shutter and optional optical isolator
- Step 3Beam steering, expansion or fiber-launch optics
- Step 4Experiment input with wavelength-matched coatings

Why this design is used
Typical uses for this laser type, with the selection logic tied to the model record.
Laboratory measurement
YL-I-638/450: Laboratory measurement benefits from a stable, focusable source. 638 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
