1.2.4 Commercial Glass Lasers
Examples of commercial glass lasers and their mode of operation (cw or pulsed),
principal wavelengths, and representative outputs are given in Table 1.2.6. These latter data
are from recent (1997–1999) laser buyers' guides and manufacturers' literature and can be
expected to change due to advances in technology.
