Series-level technical context
Engineering context for a thin CW Lasers record
This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 12 wavelength-near cw lasers records; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Typical operating fields in the series
- • Output / average power: 1~5 mW
- • Output / average power: 1~10 mW
- • Operating mode: CW
- • Power stability (rms, 4 hours ± 3°C): <2%, <1%, <0.5%
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
Application context
Why this design is used
Applications named on a datasheet for this product line, interpreted against this model’s listed wavelength and beam data.
Measurement
TEM-F-1654DFB: Measurement benefits from a stable, focusable source. 1654 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
Communication
TEM-F-1654DFB: 1654 nm emission must sit inside the fiber-component passband used for Communication; connector polish, fiber mode, linewidth and back-reflection tolerance should be specified as one optical interface.
Measurement Sensor
TEM-F-1654DFB: Measurement Sensor benefits from a stable, focusable source. 1654 nm emission fixes the compatible coatings and detector response, while M², divergence and pointing stability should be confirmed for the intended beam path.
