That a vague question.
Short answer is 175mW of 808 pump light for a DPSS 532 DX laser.
My DX 50 diode uses 350mA and the diode is about 50% efficient.
1/3 of the pump light power converts to green beam, best case.
No the diode beam needs to be focused with special short focal lenth lens then the beam is line shaped and spreads greatly over distance. You elaton optics to equalize the fast and slow axis of the diode beam to make the beam circular. I have a some pump diodes that are fast axis corrected but the beam looks square and can't be focused to a tiny spot at distance. I think lenses that are speced with radius in mm number rather than focal lenth are better suited for laser beam collimation.
The 808nm color seems weak unless it hits something dark. I can pass my finger in the beam and not feel it much because it passes through without much absorbtion.
