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.
