Table 9 - Molecular Laser Tuning Gratings

Gratings in this table are listed by laser type.

Molecular lasers have a wide variety of uses, ranging from materials processing to medical applications. These high-power lasers generally produce gain over a wide spectral range. Gratings are used in these lasers to control and narrow the lasing wavelength. The gratings below are suitable for use in the specific molecular lasers indicated.
