Texte intégralThe chirped pulse amplification (CPA) technique was developed to power scale the pulsesfrom mode-locked oscillators as the pulse energy was not sufficient to target applicationssuch as strong field physics and particle acceleration. Since its development in 1985 ithas been applied in a wide variety of commercially available laser systems and ultra-highpower laser facilities. The technique allows to circumvent the accumulation of non-linearphase which hampers pulse compression and allows to maintain the fluence of the pulsesbelow the laser induced damage thresholds (LIDT) of components. In this thesis wedevelop CPA laser systems operating at 2.05μm wavelengths with high average powerand high energy starting from the development of the seed laser up to the design andimplementation of the pulse stretcher, amplifiers and pulse compressor.In the first section of the thesis we introduce the physics background and phenomenarequired for understanding the chirped pulse amplification technique and the developmentof the seed laser. This includes dispersion, self-phase modulation and Raman scattering.In the second section of the thesis we present the development of an all-fiber polarizationmaintaining laser tunable over 170nm, from 1880nm up to 2050nm via Ramansoliton self-frequency shift (SSFS). The system is based on exclusively commercially availablestandard fibers. We have characterised the laser in terms of power, spectrum andpulse duration and we have included a post-compression stage that relies on non-lineareffects to reach the sub-100 fs duration across the whole tunability range. Simulations ofthe soliton post-compression shows the versatility of the laser which allows to customisethe pulse duration over a spectral range or for a particular wavelength. We believe thatthe laser is a versatile and robust alternative to Tm and Tm:Ho oscillators.In the third section we have tested the tunable laser in a wide variety of stretchingand compression architectures suitable for CPA. We have investigated fibers and chirpedvolume Bragg gratings (CVBG) as pulse stretching devices and grating pairs and CVBGsas pulse compressors. We discuss how to dimension a stretching-compressor pair takinginto account the non-linear phase and gain narrowing effect that takes place during pulseamplification and how to evaluate the stretching-compressor performance. Two differentchirped pulse amplification laser systems have been designed and presented, the first onetargets broadband fs pulses with high average power and the second system targets highenergetic ps pulses. The non-mature technology in the 2μm spectral region and the weakavailability of suitable stretching devices hinders pulse compression at this wavelength.In the last section of the thesis we investigated the performance of Tm:Ho co-dopedfibers in amplification configuration. We discuss the main challenges of these fibers includingthe cross-relaxation effects, the availability of pump sources which gives rise totwo main pumping schemes: diode pumping and in-band pumping and the limitations interms of fiber size. We tested Tm:Ho doped fibers, including LMA for narrowband andbroadband pulse amplification

Mode-locked lasers that produce short optical pulses in the mid-infrared wavelength region have been sought out for a wide range of applications such as free space communication, molecular spectroscopy, medical diagnostics, and remote sensing. Here, a thulium and holmium (Tm/Ho) co-doped fiber laser that mode-locks in both the solitonic and stretched-pulse regimes is used to produce ultra-short pulses in the 2 [mu]m region. Nonlinear polarization rotation technique is used where fiber nonlinearity is responsible to mode-lock the laser. The anomalous group velocity dispersion of both the single mode and gain fibers used limit the laser operation in the solitonic regime where spectral bandwidth is 10 nm and hence the pulse duration is limited to 996 fs. In order to increase the spectral bandwidth and hence get the shorter pulses the anomalous dispersion of these fibers has to compensate using normal group velocity dispersion fiber in the laser cavity. High numerical aperture fibers, which have normal group velocity dispersion around 2 [mu]m due to its large and positive waveguide dispersion, can be used to compensate the anomalous dispersion of the gain and single mode fibers. We used a high numerical aperture fiber called UHNA4 in the laser cavity in order to compensate the anomalous dispersion of other fibers and mode-locked the laser in stretched pulse regime. The spectral bandwidth of the laser increased to 31 nm with corresponding pulse duration of 450 fs measured from the interferometric autocorrelation. The laser dynamics of the Tm/Ho co-doped fiber laser is also studied while going from the stretched-pulse to solitonic regime by fiber cut-back measurements of normal dispersion fiber. It was clearly observed that both the spectral bandwidth and the pulse duration changed significantly going from one region to the other.
