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 32 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: <1.1, M²: <1.2, Beam divergence, full angle (mrad): <1, and Pointing stability (urad): <15 / <50. These are series context, not guaranteed values for 540; 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.
540: 540 nm emission can be matched to the absorption or excitation band used in Optical microscope. The stated stability or noise figure (<0.05% RIN(DC-3 MHz)) helps keep measured intensity changes attributable to the sample rather than source drift.
540: 540 nm emission can be matched to the absorption or excitation band used in Photon imaging. The stated stability or noise figure (<0.05% RIN(DC-3 MHz)) helps keep measured intensity changes attributable to the sample rather than source drift.
540: Physics experiment benefits from a stable, focusable source. 540 nm emission fixes the compatible coatings and detector response, while the listed beam characteristic (<1.1) informs waist size and propagation.
System integration
Use these checks to connect 540 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
M²: <1.1. 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 540 with the closest available models in the Fiber 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.
