A diode-pumped laser amplifier model is derived from first principles and applied to a Nd:YAG amplifier operating on the 4F 3/2 to 4I 9/2 transition at 0.946 μm. The effects of amplified spontaneous emission are included in the model and the additio

We employ a continuously tunable 100 fs pulse source to measure the time-resolved degenerate four-wave-mixing (DFWM) spectrum of an amorphous C 70 film. The observed nonlinear optical response is essentially instantaneous and electronic in origin. We

We use time-resolved degenerate four-wavemixing (DFWM) with femtosecond pulses in the wavelength range 0.74−1.7 μm to measure both phase and amplitude of all nonvanishing elements of the electronic third-order nonlinear optical susceptibility tens

Remote sensing requires efficient lasers that are tunable over a short wavelength range around a particular atmospheric absorption feature of interest. High efficiency usually implies lanthanide series lasers. Although lanthanide series lasers have s

With the goal of obtaining high energy at 946 nm, we have built and characterized a power amplifier that will be used in conjunction with our Three Module Oscillator and PreAmplifier to further increase the available laser energy. Previously we obtai
