Optical limiting properties and z-scan measurements of carbon disulfide at 2.05 μm wavelength
MetadataShow full item record
Nonlinear and optical limiting properties of carbon disulfide (CS 2 ) are characterized at 2.05 μm wavelength using a 𝑄 -switched Ho:YLF laser with high pulse energy. The nonlinear refractive index of CS 2 is measured using the z-scan technique, giving a value of (1.9±0.5)·10 −18 m 2 /W , i.e., (7.2±1.9)·10 −12 esu , for the 25 ns pulses from the Ho:YLF laser. Self-focusing and dielectric breakdown in CS 2 limited the output energy to 0.6 mJ in the optical limiting experiments for input energies of up to 150 mJ.
