摘要

The paper presents the study of thermal effects upon a semiconductor laser emission coherence for red radiation range and a diode-pumped Nd laser operating on second harmonic of green radiation range for operating temperatures (20 – 40° C). The coherence of the radiation was estimated by morphological Euler numbers of the interference patterns. A strong dependence of the interference patterns contrast on the operating temperature of emitting lasers was detected. Recommendations were given.
