Application context
Why this design is used
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
Communication
MIL-W-1573: 1573 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.
Spectrum analysis
MIL-W-1573: 1573 nm emission sets the excitation and detector-band choice for Spectrum analysis; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (<8) also controls focusing and collection geometry.
System integration
Integration and compatibility
Use these checks to connect MIL-W-1573 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Cooled method: Air Cooled · Operating temperature (℃): 15-35
- 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
- Beam divergence, full angle (mrad): <8 · Beam diameter at the aperture (1/e2,mm): <7
- 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.
