Application context

Why this design is used

Applications named on this model’s datasheet, expanded with the model’s optical specifications.

Collimation

MIL-FN-1357: Collimation benefits from a stable, focusable source. 1357 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (TEM00) informs waist size and propagation.

Laser medical treatment

MIL-FN-1357: 1357 nm emission determines compatible optics, coatings and detectors for Laser medical treatment. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.

Scientific experiments

MIL-FN-1357: 1357 nm emission determines compatible optics, coatings and detectors for Scientific experiments. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.

Optical instrumentation

MIL-FN-1357: 1357 nm emission determines compatible optics, coatings and detectors for Optical instrumentation. The catalogued beam parameter (TEM00) helps predict how the source will focus and propagate through the instrument.

System integration

Integration and compatibility

Use these checks to connect MIL-FN-1357 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Thermal management
Operating temperature (°C): 10-35
Provide the stated cooling method and keep the laser-head base thermally coupled; temperature drift moves wavelength, output power and beam pointing.
Beam parameters at the output
Transverse mode: TEM00 · M2: <1.5
Size the downstream optics from the stated beam diameter and divergence rather than from the aperture of the housing, and confirm the polarisation state before specifying isolators or polarising optics.
