The lobes on the sides of the main spot are what makes it multimode..
Oh and before anyone asks YES it burns bigtime.
it is multimode, but when you focus it , its not as long as lets say an 808nm diodes output. It's reasonable, this is with an aixiz acrylic and a 405g-1. mA to mw seem to be 1:1.
More pics , hopefully better ones soon.
Thank you , its fun and informative, testing new diodes. Kind of a small rush![]()
