ATMF102 laser module generates low noise, long coherent length, mode-hop-free, and good quality
bare, collimated and circularized laser beams.
ATMF102 is composed of 3 detachable components: laser body, collimation lens and circularizer. When
needing a bare laser beam, use only the laser body; when needing collimated beam, use the laser body
and the collimation lens; when needing collimated and circularized beam, use all the 3 components: the
laser body, the collimation lens and the circularizer. These 3 configurations are shown in Figure 1, 2 and
3 respectively.
