Different laser wavelengths, What are the shape of the laser spot?

445nm is a multi-mode, rectangular beam;
405nm is an ellipse;
808.980，780，1064，635，650 are square spot;
The rest is almost round.

What is the usage of high quality of spot?
Professional research and detection will have high requirement on the spot quality, if only for entertainment, there is no practical significance.

Different wavelength has different light emitting principle.

532nm is pumped laser;
445nm is a semiconductor laser, efficiency is relatively high;
532nm is pumped by a 808nm, so the efficiency is low;
445nm is direct emitting by a 445nm diode;
Blue light emitting easily, it can light directly after add the lens alignment.
532nm required to process very high technical.
