"NettetTalking about SM laser diode beam circularization, a pair of anamorphic prisms is often the case (see Fig. 3). A collimated elliptical beam can be circularized by either expanding in the slow axis of the ellipsis or compressing in the fast axis direction. After propagation through the prisms, a minor lateral beam displacement occurs. " - Led fast and slow axis

NettetSome micro-optics approaches utilize a small cylinder lens mounted internally, which slows down the diverging fast axis beam. This lens is incorporated into an existing laser diode unit. This method does not produce a collimated beam and an external collimating lens is still needed. The value-added benefit NettetAs an example, an FWHM beam divergence angle of 30° may be specified for the fast axis of a small edge-emitting laser diode. This corresponds to a 25.4° = 0.44 rad 1/e 2 half-angle divergence, and it becomes apparent …
