METHOD OF CHANGING NORMAL REFRACTION INDEX OF NONLINEAR GaSe CRYSTAL |
| 摘要 |
FIELD: physics.SUBSTANCE: invention can be used when making parametric frequency converters of laser radiation in the middle infrared and terhertz spectral range. The normal refraction index of a nonlinear GaSe crystal is changed by doping with chemical element Al with a small size compared to the chemical element Ga in concentration of 0.005-0.05 wt %.EFFECT: increasing refraction index for normal polarisation waves in GaSe crystals with minimal changes in the refraction index for unusual polarisation waves.1 tbl |
