Sudden Change of Phase Shift of Dichroic Mirrors Used in Femtosecond Ti:Sapphire Laser
Phase shift and dispersion properties of dichroic mirror used in femtosecond Ti:sapphire laser are investigated. A sudden change of reflective phase shift near central wavelength is observed. Because of this transition point the second and third order dispersion have a discontinuous point. The factors affecting the transition point are discussed in detail.
