Application context
Applications named on this model’s datasheet, expanded with the model’s optical specifications.
MIL-W-4200: 4200 nm emission sets the excitation and detector-band choice for Spectroscopy; linewidth and wavelength stability determine how cleanly weak spectral features can be separated from the laser line. The listed beam characteristic (<11) also controls focusing and collection geometry.
MIL-W-4200: 4200 nm emission determines compatible optics, coatings and detectors for Remote sensing. The catalogued beam parameter (<11) helps predict how the source will focus and propagate through the instrument.

Technical FAQ
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 divergence, full angle (mrad): <11 · Beam diameter at the aperture (1/e2,mm): <11. 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.
Share wavelength, operating mode, output power or pulse energy, linewidth or pulse width, delivery, control, and safety requirements and we will qualify the matching configuration and lead time.
