Laser diode m2
M is useful because it reflects how well a laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. Likewise, a beam intensity profile can appear very "un-Gaussian", yet have an M value close to unity. It is defined as the beam parameter product (BPP) divided by λ / π, where λ is the wavelength. Nevertheless, M² is a simple, widely-used metric for characterizing laser beams. Pricing (USD) Filter the results in the table by unit price based on your quantity.
