Neodymium glass sweep laser 'Spektr 2-6'

The paper describes the characteristics and structure of the optical and electronic blocks of a neodymium glass sweep laser operating at low sweep velocities. The emission spectrum of the laser is a set of discrete lines at intervals from 0.5 to 2 A, the width of each individual line being about 0.1 A. Frequency range during bursts is from 5 to 170 A, depending on sweep velocity. The emission spectrum can be smoothly varied within a 500 A range. The laser can be used for studying the many dispersion relations appearing in the interaction of coherent radiation with matter, whereby nearly all the necessary information can be obtained in one pulse (0.001 sec). A setup for a slotless laser spectrometer used to measure the spectral contour of the gain coefficient of garnet crystal doped with neodymium is illustrated.-
