This book was released on 2008 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in fully-stabilized mode-locked laser systems are enabling many applications, including optical arbitrary waveform generation (OAWG). In this thesis work, we describe the development of high repetition-rate fiber laser-based systems for the realization of these applications at 1550 nm wavelengths. To realize these systems, frequency comb sources are needed that are compatible with electric field stabilization techniques, are compatible with integrated arrayed waveguide grating and modulator technology, and have high repetition rates to allow full use of current modulator bandwidths. Erbium-doped fiber lasers are one of the leading options to fill this role. To that end, fundamentally mode-locked stretched pulse fiber lasers approaching 250 MHz repetition rate and soliton fiber lasers at over 200 MHz repetition rates are presented, and the limitations of repetition rate scaling in fiber lasers are explored. Using the 200 MHz soliton laser and an external Fabry-Perot cavity, a low-noise, repetition rate multiplied 2 GHz source is demonstrated. Stabilization systems for high repetition rate sources must also be developed. Carrier envelope offset locking experiments using self-referencing techniques at 200 MHz repetition rate are described. Initial demonstrations towards repetition rate locking to a methane-stabilized HeNe single-frequency standard using difference-frequency generation are presented.

This book was released on 2012 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond lasers and the development of frequency combs have revolutionized multiple fields like metrology, spectroscopy, medical diagnostics and optical communications. However, to enable wider adoption of the technology and new applications like photonic sampling, optical arbitrary waveform generation or the calibration of astronomical spectrographs, multi-GHz repetition rate femtosecond lasers with robust performance metrics, low cost, and a compact footprint are highly desirable. In this thesis, different approaches to develop GHz mode-locked laser systems at telecommunication wavelengths are discussed and current achievements presented. Design aspects for constructing a long-term stable and compact fiber laser with 187 fs short pulses at a repetition rate of 1 GHz are covered. In order to scale the repetition rate into the multi- GHz regime, coherent pulse interleaving in novel thermally tunable waveguide interleavers is demonstrated at 10 GHz. A femtosecond erbium-doped waveguide laser is developed at GHz repetition rates and important design guidelines are provided. As saturable Bragg reflectors are crucial in all of the described systems to enable mode-locking, saturable absorber optimization is discussed and their optical performance compared. Thus, this research paves the way for compact, affordable high repetition rate fiber lasers and monolithically integrated femtosecond laser sources which can be combined on-chip with additional functionalities to develop novel photonic systems with impact on spectroscopy, sensing, telecommunications and biomedical applications.

Book excerpt: This thesis reports work in high repetition rate femtosecond fiber lasers. Driven by the applications including optical arbitrary waveform generation, high speed optical sampling, frequency metrology, and timing and frequency distribution via fiber links, low noise fiber laser sources operating at multi-gigahertz repetition rates are developed systematically. A 200 MHz fundamentally mode-locked soliton laser and a 200 MHz fundamentally mode-locked similariton laser are first developed. Intra-cavity soliton formation is recognized as the optimum route towards achieving high fundamental repetition rates compact lasers, under the limitation of realistically available pump power. A 3 GHz fundamentally mode-locked femtosecond fiber laser is developed and verifies the soliton formation theory. Techniques in external cavity repetition rate multiplications are also discussed. A theoretical model that relates the repetition rate of the soliton laser and its other physical measurable parameters is developed to guide further high repetition rate laser development.

This book was released on 2006 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This thesis has documented the development of a MHz repitition rate pulse burst laser system. Second harmonic and third harmonic efficiencies are improved by adding a Phase Conjugate Mirror to the system. Some high energy fundamental, second harmonic, and third harmonic burst sequences consisting of 1 - 12 pulses separated in time by between 4 and 12 microseconds are now routinely obtained. The reported burst envelopes are quite uniform. We have also demonstrated the ability to generate ultra-high frequency sequences of broadly wavelength tunable, high intensity laser pulses using a home built injection seeded Optical Parametric Oscillator (OPO), pumped by the second and third harmonic output of the pulse burst laser. Typical OPO output burst sequences consist of 6 - 10 pulses, separated in time by between 6 and 10 microseconds. With third harmonic pumping of the OPO system, we studied four conditions, two-crystal Singly Resonant OPO (SRO) cavity, three-crystal OPO cavity, single pass two-crystal Doubly Resonant OPO (DRO) cavity and double pass two-crystal OPO cavity. The double pass two-crystal OPO cavity gives the best operation in burst mode. For single pass OPO, the average total OPO conversion efficiency is approximately 25%. For double pass OPO, the average total OPO conversion efficiency is approximately 35%. We have also demonstrated injection seeding for OPO. The OPO output light linewidth is significantly narrowed. Some preliminary etalon traces are also reported. By mixing the OPO signal output at 622 nm with residual third harmonic at 355 nm, we obtained 226 nm burst sequences with average pulse energy of ~0.2 mJ. Injection seeding of the OPO increases the energy achieved by a factor of ~2. 226 nm burst sequences with reasonably uniform burst envelopes are reported. Using the system we have obtained, for the first time by any known optical method, Planar Laser Induced Fluorescence (PLIF) image sequences at ultrahigh (100kHz) frame rates, in particular NO PLIF image sequences, have been obtained in a Mach 2 jet.
Download or read book Continuously Tunable High Repetition Rate RF Excited CO2 Waveguide Laser written by Stian Loevold and published by . This book was released on 1982 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of pumping a CO2 laser with a radiofrequency discharge at multiatmospheric pressures in order to obtain continuous frequency tuning has been investigated both theoretically and experimentally. Experimentally 40.68 MHz rf-excitation of discharges between parallel plate electrodes with up to 7-8 kW peak rf-power has been investigated. Emphasis has been laid on how to attain a stable glow-discharge with sufficiently long duration before arcing for integration of enough rf-power in the discharge to reach threshold for laser oscillation. A 10 atm rf-excited CO2 waveguide laser has been developed. With no dispersive elements in the laser resonator and with a 2% output coupler, input rf-power threshold for laser oscillation was 2 kW at 10 atm. Peak output power was 1.5 kW for 7-8 kW input rf-power. The output pulse has the form of a 300 ns duration gain-switched pulse followed by a tail at lower power. An efficiency (input rf-energy/laser output-energy) of 2% has been measured for the gain-switched pulse. The laser has been operated with pulse repetition rates in excess of 1 kHz, limited primarily by the available gas-flow capacity. Continuous frequency tuning between the R(12) and R(14) lines in the 10.4-micrometer band has been demonstrated. (Author).
