Series-level technical context
This model has no standalone PDF and only a small number of model-specific rows. The values below are traceable context from 113 nearby configurations on the same source-product record; they define the parameters to qualify, but are not substituted for an order-specific datasheet.
Nearby series records state M²: <1.5, M²: <1.2, Beam divergence, full angle (mrad): <1.0, and Beam divergence, full angle (mrad): <1.2. These are series context, not guaranteed values for 800; confirm them on the order-specific datasheet.
Application context
Applications named on a datasheet for this product line, interpreted against this model’s listed wavelength and beam data.
800: 800 nm emission can be matched to the absorption or excitation band used in Optical microscope. The stated stability or noise figure (/) helps keep measured intensity changes attributable to the sample rather than source drift.
800: 800 nm emission can be matched to the absorption or excitation band used in Photon imaging. The stated stability or noise figure (/) helps keep measured intensity changes attributable to the sample rather than source drift.
800: Physics experiment benefits from a stable, focusable source. 800 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (<1.5) informs waist size and propagation.
System integration
Use these checks to connect 800 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
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.
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.
Model selection
Compare 800 with the closest available models in the Single-Frequency Lasers family. Confirm option-dependent values on the final configuration before ordering.

Choosing a laser
Which specifications decide the experiment, and which ones cost money without changing the result.
PhotonicsLinewidth, spectral width, RIN, M², and coherence length answer five different questions. Translate each into the units your experiment is designed in — and learn which ones not to pay for.

PhotonicsSingle-mode fiber does not preserve polarization. Pin the state, erase it with a scrambler, or maintain it in PM fiber — which one your measurement needs, and the response time and extinction ratio that decide it.
