In other words, a green DPSSL using a 2.5 W pump diode would be expected to output around 500-900 mW of 532 nm light. In optimal conditions, Nd:YVO 4 has a conversion efficiency of 60%, [1] while KTP has a conversion efficiency of 80%. [2] In other words, a green DPSSL can theoretically have an overall efficiency of 48%.
In comparison, the conventional diode-pumped solid-state lasers (DPSSLs) on the market used diode bars as the pump source, with each bar typically producing 40 W of power. [ 22 ] By the end of 2000, capital spending by telecommunications providers was reduced and IPG revenue from communications applications declined.
A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.

Solid state lasing media are typically optically pumped, using either a flashlamp or arc lamp, or by laser diodes. [1] Diode-pumped solid-state lasers tend to be much more efficient and have become much more common as the cost of high-power semiconductor lasers has decreased.
A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance). It has low (ideally zero) ...
Other achievements, important particularly for laser applications, concern the development of mode-locked lasers that can be pumped with laser diodes, can generate very high average output powers (tens of watts) in sub-picosecond pulses, or generate pulse trains with extremely high repetition rates of many GHz.
Dye lasers are very versatile. In addition to their recognized wavelength agility these lasers can offer very large pulsed energies or very high average powers. Flashlamp-pumped dye lasers have been shown to yield hundreds of Joules per pulse and copper-laser-pumped dye lasers are known to yield average powers in the kilowatt regime. [27]
