| Abstract: | A background-free measurement of an individual pulse of a passively mode-locked Nd: glass laser during one laser shot has been performed using a crystal of LiIO3. The method is based on the non-collinearly generated second harmonic intensity spatial distribution measurement. The time resolution was better than 0.1 ps. The method can be successfully used for picosecond pulse measurement of any laser source over a wide wavelength region. |
