Luminesce (dielectric crystals and glass) solid-state lasers. [2] Figure 5. In solid-state lasers, it is carried out by means of irradiation with powerful gas-discharge flash lamps, with focused solar light (the so-called optical pumping) or with other lasers (in particular, semiconductor). Pulsed lamps convert electrical energy into optical energy more efficiently than diode lasers do ( 80% efficiency as compared to 30% – 50% efficiency in tube lasers), but due to the inefficient pump radiation absorption, the efficiency of lamp-pumped Nd lasers is, as a rule, only 1% while the efficiency of diode-pumped lasers is 10%. Modern solid-state lasers are capable of operating in a pulsed, continuous, and quasi-continuous modes. Figure 2  shows the absorption spectrum of the most common solid-state laser material (Nd: YAG), and the output spectrum of a flash lamp and a diode laser, illustrating increased efficiency. Laser components. This stored energy can be released in a 10-nsec pulse, using Q-switching, which results in a peak output power 10 ^ 4 times bigger than that of the laser diode. to the main level (or from Е3 to the auxiliary level Е2 in a four-level system). Continuous arc lamps, pulsed flashlamps and more recently diode lasers are used commercially.
