Performance Enhancement of the Solid Saturable Absorber for Laser Passive-Switching at 1.353 μm

Abstract

In order to approach the ideal conditions to optimized the performance of the 10mm CaF2 crystal which is containing(5%) standard mixing of uranium ions as proposal saturable absorber element model for Q-switching laser operation in the spectral wave length around 1.353 μm, the main aspects of this investigation are accomplished by means of the analytical treatments and direct calculations of derived equations as well as several programmed plotted graphs are obtained and applied to evaluated the most important active influences parametric and its effect on this type passively Q-switching laser operation such as, the output pulse peak power, the pulse energy, the depth modulation as well as the absorption cross-section and the nonlinear reflectivity . The comparing of the interpolated results for this work with the different wave length ranges and by another materials types are strongly agreed with the earlier researchers calculations . Slightly different with some researcher measurements were owing to experiment errors as well as, which were because of the close estimations and the high precise treatments of this work . The errors percentage were only 4-5.8%, which are seem insignificant its influences on the essential goals for this work The results are very satisfied to applied this proposal model as optimum controlling element for the passively Q-switching laser operation at 1.353 μm ●
