### Red vs green laser: power question? : lasers

That being said, a 5mW green will be the same light output as a 5mW red diode. However, a DPSS green is less energy efficient than a red, because it's actually using a higher power IR diode to pump crystals to get green light. The difference between a red diode, and a direct diode green, might be very very similar.

### Parameter Overview of Laser Diodes by Dr. Kamran S. Mobarhan

This means, that the efficiency of a real laser, in converting input current to output light, is the ratio of its associated ∆P/∆I parameter to hc/qλ. Since both terms ∆P/∆I and hc/qλ have the same units of Watt/Amp, the resultant term: (∆P/∆I) / (hc/qλ) is a unit-less parameter given in a percentage form.

### ELI5: DPSS vs Diode : lasers - reddit

The main difference between diode and DPSS is that the DPSS has another lasing medium that provides the specified output. Take a simple Nd:YAG. You will be pumping the YAG rod with a lower power diode. The YAG has specific absorption wavelengths, which is what the diode provides. At this point, the light is amplified, and wavelength is converted.
