  1. 1. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Saga Westerberg; [2023]
    Keywords : Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

    Abstract : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index.

  3. 2. Development of optimized Raman Spectroscopy setup for species detection in flames

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Henrik Johansson; [2016]
    Keywords : multi-pass; Raman; spectroscopy; species concentration; flames; combustion; Stokes; high-power laser; Physics and Astronomy;

    Abstract : A multi-pass Raman spectroscopy setup, consisting of a measuring cell built as a cavity, using two concave circular mirrors, has been constructed and optimized. As the light reflects between the mirrors, the Stokes Raman signal is enhanced with every pass through the cavity. READ MORE
