solid state lasers

https://doi.org/10.1351/goldbook.S05736
CW or pulsed lasers in which the active medium is a solid matrix (crystal or glass) doped with an ion (e.g. Nd3+ , Cr3+ , Er3+). The emitted wavelength depends on the active ion, the selected optical transition, and the matrix. Some of these lasers are tunable within a very broad range (e.g. from \(700\) to \(1000\ \text{nm}\) for Ti3+ doped sapphire). Pulsed lasers may be free-running, Q-switched, or mode-locked. Some CW lasers may be mode-locked.
