“…Therefore, longer interaction lengths and higher nonlinearities are required. As mentioned in Section 2.1.2.1, high nonlinearities can be achieved with organic materials, such as DAST, which is phase matchable for type I and type II conditions, and N-(4-nitrophenyl)-L-prolinol (NPP) [67,68]. Those materials are often used for terahertz generation and mode-locking.…”

This thesis reports a new active power stabilization scheme which can be implemented in high precision experiments, such as gravitational wave detectors. The novel aspect of the scheme is sensing laser power uctuations via the radiation pressure driven motion they induce on a movable mirror. The mirror position and its uctuations are determined by means of a weak auxiliary beam and a Michelson interferometer, which form an in-loop sensor for the proposed stabilization scheme. This sensing technique exploits the concept of a nondemolition measurement, since the power uctuations are inferred by measuring the uctuations in the phase observable of the auxiliary beam. This process results in higher in-loop signals for power uctuations than what would be achieved by a direct detection, e.g. via the traditional scheme where a fraction of the laser power is picked o and sensed directly by a photodetector. Other advantages of this scheme are that the full beam power is preserved and available for further use, and that it enables the generation of a strong bright squeezed out-of-loop beam.An extensive theoretical investigation on the concept of the new sensing scheme is presented. In this investigation, di erent schemes in which power uctuations are transferred to another observable of the light eld, e.g. phase or polarization, are compared to each other, and the advantages of the radiation pressure scheme are highlighted. Furthermore, a complete calculation of the fundamental limit of the proposed radiation pressure scheme, set by the quantum noise in the interferometer and the thermal noise of the movable mirror, is performed. The calculations show that a bright squeezed beam with a power of 4 W and up to 11 dB of squeezing might be achievable in the near future. Based on the results of the theoretical investigation, a proof-of-principle experiment was realized with microoscillator mirrors with masses ranging from 25 to 250 ng, and fundamental resonance frequencies from 150 to 210 Hz. Power stabilization in the frequency range from 1 Hz to 10 kHz was demonstrated. The results for the out-of-loop power stability are presented for di erent beam powers, and a relative power noise of 3.7 × 10 −7 Hz −1/2 was achieved at 250 Hz for 267 mW. The stability performance was limited by the structural thermal noise of the micro-oscillators, which was particularly high due to operation at room temperature. The results from the investigations conducted in this thesis are a promising step towards generation of a strong bright squeezed beam, and towards an improved stabilization scheme to be used in the future generation of gravitational wave detectors.

“…In the experiment, they clearly demonstrated large nonlinear phase shifts. This experiment paved the way to the experimental investigation in other nonlinear quadratic materials: ␤-barium borate by means of self-diffraction, 12 potassium niobate, 13 potassium dihydrogen phosphate, 14 organic N-(4-nitrophenyl-Lprolinol, 15 and periodically poled lithium niobate. 16 A theoretical description of nonlinear phase distortions in (2) materials was made by numerical integration of the nonlinear differential equations that describe the propa-gation of plane waves.…”

All-optical switching in a high- Q Fabry–Perot cavity filled with a quadratic material

A theoretical analysis of the nonlinear quadratic interaction between two monochromatic plane waves at frequencies and 2 in a Fabry-Perot cavity shows that all-optical control of reflectivity and transmissivity of the fundamental beam is possible under suitable conditions. We report all-optical switching of the fundamental beam for cavity lengths that vary from a few micrometers to a few millimeters. Specifically, we show that 100% all-optical switching can occur for a 6-m cavity when the nonlinear coefficient is not greater than 20 pm/V and the input intensity does not exceed 10 GW/cm 2. Our analytical results are obtained without use of the slowly varying envelope approximation and without resort to the undepleted-pump approximation.

“…Design and synthesis of efficient organic nonlinear optical (NLO) materials are very important due to their potential applications in the fields of telecommunication, optical data storage and optical information processing. Nitrophenyl derivatives are NLO materials1–3 and have been used for a very efficient frequency‐conversion process based on cascading 4. Zyss et al 5 reported the NLO properties of N ‐(4‐nitrophenyl)‐ L ‐prolinol.…”

Fourier transform (FT)-Raman and infrared (IR) spectra of the nonlinear optical (NLO) material bis(4-nitrophenyl) carbonate were recorded and analyzed. The geometry, first hyperpolarizability and harmonic vibrational wavenumbers were calculated with the help of Becke3-Lee-Yang-Parr density functional theory method. The detailed interpretation of the vibrational spectra was carried out with the aid of normal coordinate analysis following the scaled quantum mechanical force field methodology. The second-order NLO properties of the molecule were studied by the Kurtz and Perry powder reflection technique. Stability of the molecule arising from hyperconjugative interactions leading to its NLO activity and charge delocalization were analyzed using natural bond orbital analysis.
