We demonstrate the use of kW class, high energy pulsed nanosecond lasers for surface cleaning applications. A hybrid ablation-detachment process allows removal rates of semi-transparent paint from primer at 40,000 mm3 /kW.min. The process shows a thr

We present a 400 W Q-switched 532 nm laser using several techniques to control the pulse duration and shape. The laser consists of two separate intracavity frequency-doubled cavities, incoherently combined to give 50 mJ total pulse energy. By extendi

A high-power green picosecond laser based on the ‘Z-slab’ Nd:YAG amplifier is presented. The edge-pumped zigzag amplifier was designed to achieve high energy scaling with good beam quality. In a master oscillator power amplifier system 120 W aver

We demonstrate power scaling of an Nd:YAG picosecond master oscillator power amplifier system to over 200 W. The ‘z-slab’ amplifier design is a power scalable, edge-pumped zigzag slab amplifier architecture, and it is demonstrated here in two alt

We demonstrate 220 W average power at 355 nm from a diode-pumped acousto-optically Q-switched Nd:YAG laser using intracavity second harmonic generation and sum frequency mixing in a nested sub-cavity design. The laser generates linearly polarised pul

We report on the laser drilling and cutting of 2 mm thick CFRP with the Rigel g200; a green, Q-switched diode-pumped solid-state (DPSS) Nd:YAG laser system. The laser beam was delivered with a 600 × 600 µm square core fibre to produce an average ou

A new high power laser optical system has been developed which is operated by pulsed, green, diode pumped solid state lasers. The design is based on multiplexing of lasers by fiber coupling and is scalable to power levels above 1.6kW. The combined hi

A new design of the laser resonator using dual phase conjugation mirrors is discussed. It is shown that using the modified Gerchberg-Saxton algorithm, phase conjugation criteria at the both mirrors with finite apertures can be met for the given shape
