Book Description
A source-demand in the near- and mid-IR wavelength spectrum exists for various applications such as waveguide inscription, multiphoton imaging, and nonlinear spectroscopy. All of the applications seek for higher repetitions rates for faster processing speed, better signal to noise ratios or to improve the results for applications like laser waveguide inscription. This is in contrast to the high pulse energies, required to drive the nonlinear processes involved with these applications. Available systems are either based on low-energy, high-repetition-rate optical parametric oscillators or high-energy, low-repetition-rate optical parametric amplifiers. In this thesis a sources was developed that can bridge the wide gap between these two extremes, providing sufficient energy to drive nonlinear processes, with repetition rates in the MHz domain. This was achieved by introducing three techniques previously employed for energy scaling in laser cavities. Firstly an exchange from the conventionally used Ti:sapphire pump to a commercial high power Yb:fibre laser system readily scaled the usable pump energy. This was combined with a technique known as cavity-length extension, which allows a lowering of the cavity roundtrip time offering the build-up of pulses with increased energy. In a final stage, cavity-dumping on basis of an acousto-optic modulator was introduced into the a redesigned cavity. The combination of these three techniques, novel to synchronously pumped optical parametric oscillators, enabled the extraction of record-high pulse energies and peak powers.

Book Description
Ultrashort Laser Pulse Phenomena, Second Edition serves as an introduction to the phenomena of ultra short laser pulses and describes how this technology can be used to examine problems in areas such as electromagnetism, optics, and quantum mechanics. Ultrashort Laser Pulse Phenomena combines theoretical backgrounds and experimental techniques and will serve as a manual on designing and constructing femtosecond ("faster than electronics") systems or experiments from scratch. Beyond the simple optical system, the various sources of ultrashort pulses are presented, again with emphasis on the basic concepts and how they apply to the design of particular sources (dye lasers, solid state lasers, semiconductor lasers, fiber lasers, and sources based on frequency conversion). - Provides an easy to follow guide through "faster than electronics" probing and detection methods - THE manual on designing and constructing femtosecond systems and experiments - Discusses essential technology for applications in micro-machining, femtochemistry, and medical imaging

Book Description
Examining classic theories, experimental methods, and practical formulas for exploration of the core topics in nonlinear optics, the second edition of this acclaimed text was extensively revised to reflect recent advances in the analysis and modification of material properties for application in frequency conversion, optical switching and limiting, multiphoton absorption, and electro-optic effects. Handbook of Nonlinear Optics, Second Edition contains additional chapters on ultrafast characterization techniques, laser flash photolysis, and the electro-optic effect as well as expanded coverage of nonlinear optics in fibers and pulsed two-beam coupling.

Book Description
This thesis reports experimental indirect spectral transfer of shaped pulses from the near to mid-infrared via the use of an optical parametric oscillator. It was shown that good spectral fidelity of transfer can be achieved by making suitable adjustments to the OPO. The issues affecting the transfer process are discussed and experimental results are compared with existing theory. The shaping of the nearinfrared pulses was performed using a zero dispersion pulse shaper and a computer controlled spatial light modulator. A suitable search algorithm was written and, with the use of appropriate computer hardware, allowed a closed-feedback loop to be implemented. The computer controlled hardware was demonstrated to be able to autonomously optimise simple experiments in the mid-infrared and optimise the threshold of an optical parametric oscillator.
