Fundamental Limitations in the Measurement and Stabilization of the Carrier-Envelope Phase of Ultrashort Laser Pulses - Bok av Sebastian Koke - Häftad

Fundamental Limitations in the Measurement and Stabilization of the Carrier-Envelope Phase of Ultrashort Laser Pulses - Bok av Sebastian Koke - Häftad

The stabilization of the carrier-envelope phase of ultrashort laser pulseswent through a rapid development from the first publication of a feasibleconcept in 1999 to being a mature tool for frequency metrology and attosecondscience now. Using this technique, stabilization of the timing between thecarrier wave and the envelope of a laser pulse with residual jitters of only 100attoseconds has become possible. Naturally, the questions arises whether andhow this can be further improved.The current work..

Development and characterisation of a diode laser based tunable high-power MOPA system (Band 51) - Bok av Mahmoud Tawfieq - Häftad

Development and characterisation of a diode laser based tunable high-power MOPA system (Band 51) - Bok av Mahmoud Tawfieq - Häftad

The aim of this work is to develop and characterize widely tunable high-power diode lasers emitting at 976 nm, targeting non-linear frequency conversion applications. This was realized by a master oscillator power amplifier (MOPA) configuration, where the MO provides wavelength stabilization and tuning, while the PA ensures power amplification to the watt level. Two approaches of developing tunable laser sources were investigated.In the first approach, three types of monolithic multi-arm lasers were..

Optimization of broad-area GaAs diode lasers for high powers and high efficiencies in the temperature range 200-220 K - Bok av Frevert Carlo - Häftad

Optimization of broad-area GaAs diode lasers for high powers and high efficiencies in the temperature range 200-220 K - Bok av Frevert Carlo - Häftad

This work focuses on the development of AlGaAs-based diode laser (DL) bars optimized for reaching highest powers and efficiencies at low operation temperatures. Specifically, the quasi continuous wave (QCW) pumping of cryogenically cooled Yb:YAG solid-state lasers is targeted, setting requirements on the wavelength (940 nm), the pulse conditions (pulse length 1.2 ms) and frequency (10 Hz) as well as the lowest DL operating temperature THS ~ 200 K, consistent with economic cooling. High fill-factor..
