    Direct imaging through scattering media by use of efficient third-harmonic generation in organic materials
    (Georgia Institute of Technology, 2004-11) Ramos-Ortiz, Gabriel ; Cha, Myoungsik ; Kippelen, Bernard ; Walker, Gregory A. ; Barlow, Stephen ; Marder, Seth R.
    We report on real-time, time-gated, direct imaging through scattering media with an attenuation of 14 mean-free paths by use of third-harmonic generation in the eye-safe and telecommunication-compatible near-IR spectral region (1550 nm).

    Ultrafast-pulse diagnostic using third-order frequency-resolved optical gating in organic films
    (Georgia Institute of Technology, 2004-10) Ramos-Ortiz, Gabriel ; Cha, Myoungsik ; Thayumanavan, S. ; Mendez, J. C. ; Marder, Seth R. ; Kippelen, Bernard
    We report on the diagnostic of ultrafast pulses by frequency-resolved optical gating (FROG) based on strong third-harmonic generation (THG) in amorphous organic thin films. The high THG conversion efficiency of these films allows for the characterization of sub-nanojoule short pulses emitting at telecommunication wavelengths using a low cost portable fiber spectrometer.

    Third-order optical autocorrelator for time-domain operation at telecommunication wavelengths
    (Georgia Institute of Technology, 2004-07) Ramos-Ortiz, Gabriel ; Cha, Myoungsik ; Thayumanavan, S. ; Mendez, J. C. ; Marder, Seth R. ; Kippelen, Bernard
    We report on amorphous organic thin films that exhibit efficient third-harmonic generation at telecommunication wavelengths. At 1550 nm, micrometer-thick samples generate up to 17 mW of green light with input power of 250 mW delivered by an optical parametric oscillator. This high conversion efficiency is achieved without phase matching or cascading of quadratic nonlinear effects. With these films, we demonstrate a low-cost, sensitive third-order autocorrelator that can be used in the time-frequency domain.
