Laser Transitions in Neutral Atomso the quantum state . = 2 (Balmer series) involve the emission of radiation at wavelengths 410, 434, 486 and 656 nm, amongst others. However, laser operation in hydrogen atoms is prevented by the formation of stable H. molecules under normal conditions. Hence, dissociation of the molecules would be

Solid-State Lasers the form of ions. Aside from conventional rods and slabs with lengths of several cm, technologies based on disks or fibers with thicknesses, respectively diameters of 10 to 100 µm become more and more prevalent. Most solid-state lasers are based on transition metal ions such as Ti, Cr and Co or rar

Semiconductor Lasersreported by Robert N. Hall and others in 1962 using a diode structure. Initially, the operation was restricted to pulsed mode at low temperatures. With the invention of the double heterostructure (Sect. .), continuous wave lasing at room temperature was achieved in 1970. Today, semiconductor diode l
