It's often accepted that green DPSS lasers can be up to about 35% efficient (although these are extremely rare), and any green laser with over 20% efficiency is considered exceptional. This is consistent with the fact that green lasers using 2.5W pump diodes are considered "good" if they output over 500 mW (or even 600 mW) of green light.
However, does anyone know the approximate efficiencies of blue (473 nm) and yellow (589.5 nm) lasers? Thanks.
