    Summary

    For optimal laser performance, Nd:YLF and Nd:YVO(4) crystals are recommended for generating short pulses with high slope efficiency. These materials outperform Nd:YAG and Nd:strontium fluorovanadate (S-VAP) under specific conditions.

    Area of Science:

    • Laser Physics
    • Materials Science

    Background:

    • Optimizing laser performance is crucial for various scientific and industrial applications.
    • Selecting the right host material significantly impacts laser efficiency and pulse characteristics.

    Purpose of the Study:

    • To identify the optimal host material for simultaneous generation of short pulse width and high slope efficiency in lasers.
    • To compare the performance of Nd:YAG, Nd:YLF, Nd:YVO(4), and Nd(3+):Sr(5)(VO(4))(3)F [Nd:strontium fluorovanadate (S-VAP)] laser crystals.

    Main Methods:

    • Characterization of four different neodymium-doped laser crystals under end-pumped and frequency-modulation mode-locking conditions.
    • Measurement of key laser performance parameters: slope efficiency, threshold pump power, and pulse width.
    • Comparison of experimental results with theoretical predictions and definition of a figure of merit.
