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.
Communication
PGL-D12-445: 445 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
PGL-D12-445: 445 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 (Near TEM00) also controls focusing and collection geometry.
System integration
Integration and compatibility
Use these checks to connect PGL-D12-445 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Thermal management
- Operating temperature: 0°C to 40°C
- 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: Near TEM00 · Beam diameter at the aperture(1/e2) (mm): ~3.5
- 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.
