I noticed people talking about the xxxxxG84 638nm, then saw them talking about 3W of pulsed 638nm coming next like it was (exciting). Stumbled on this and thought I was bringing something special or new to the table on that notion. Whoops! Pardon me.Hi,
The twin beam diode is definitely a strange one. Thats why I purchased the diodes , there are a few left online see time to time. I purchased them out of curiosity . But they are cool.
The raw divergence from the emitter is due to the geometry of the cavity, wavelength, etc.Here's one for you guys:
If multiple beams travel away from an alike plane, is their angle of separation, which remains relative with divergence, is it a value strictly designed by mfgr or inherent?
This is true, but only before you collimate the multiple beams. After collimation the far field is just an image of the emitters including the space between them.If two beams started from two parallel origination points on chip substrate that are only say 50um apart, ideally at infinity they are still 50um offset beams but with apparent total overlap to human eye--even after mere millimeters of travel distance.
No clue?Are the modes occurring within the cavity quantitatively field reacting under excitation, leading to electromagnetically squeezed/pressured states that cause axis non-parallelism?
Yes.To further the issue even moreso, couldn't one of two beams be knife-edged out, reflected via mirrors to then enter a PBS cube that the other beam entered with correct polarization, and beams be stacked very closely to form a single beam 638nm?
So someone should be knife edging single diodes by now!The raw divergence from the emitter is due to the geometry of the cavity, wavelength, etc.
This is true, but only before you collimate the multiple beams. After collimation the far field is just an image of the emitters including the space between them.
