Their aim was to put their scientific knowledge and experience into practice and to develop optical thin film components for high performance compact femtosecond laser sources. We at R&D Ultrafast Lasers Ltd. are constructing and manufacturing tunable femtosecond pulse lasers such as Ti:sapphire lasers, femtosecond pulse Optical Parametric Oscillators (OPO-s) and fixed wavelength, sub-ps pulse Yb-fiber lasers and amplifiers for applications in nonlinear microscopy, such as two-photon excitation fluorescence (TFEF), second-harmonic generation (SHG) and coherent anti-Stokes Raman Scattering (CARS) microscopy.
