…keep the laser diode at a constant temperature. The laser beam can be modulated by an external signal and all models can operate in either CW or external modulation mode. The standard unit provides voltage outputs proportional to the beam power, laser diode current and laser diode temperature, for…

…using vernier
callipers. A commonly used definition of beam
width is the width at which the beam intensity
has fallen to 1/e² (13.5%) of its peak value.
This is derived from the propagation of a
Gaussian beam and is appropriate for lasers
operating in the fundamental…

…laser beam in the Far Field will be M² times larger than calculated for a perfect
Gaussian beam. In other words, M² describes how close to "perfect-Gaussian" a laser beam is. For a perfect
Gaussian beam, M² is 1. For a non-prefect Gaussian beam, M² is >1.
