05736 IUPAC Gold Book - solid state lasers 10.1351/goldbook.S05736 S05736 current 1 CW or pulsed lasers in which the active medium is a solid matrix (crystal or glass) doped with an ion (e.g. $\ce{Nd^{3+}}$, $\ce{Cr^{3+}}$, $\ce{Eu^{3+}}$). 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 \(1000\ \rm{nm}\) for $\ce{Ti^{3+}}$ doped sapphire). Pulsed lasers may be free-running, Q-switched, or mode-locked. Some CW lasers may be mode-locked. active medium https://goldbook.iupac.org//terms/view/A00106 mode https://goldbook.iupac.org//terms/view/M03958 wavelength https://goldbook.iupac.org//terms/view/W06659 PAC, 1996, 68, 2223.
