Pulsed laser system NanoFlux AWG

nanosecondQ-switchedsolid-state

The NanoFlux AWG series are temporally shaped high energy Nd:YAG lasers designed for advanced scientific and industrial applications. The main feature of these lasers is the ability to shape output pulses temporally, achieved through an electro-optical modulator driven by a programmable arbitrary waveform generator (AWG).

Features

• High energy nanosecond lasers
• Temporally shaped pulses
• Up to 10 J pulse energies
• 10 Hz pulse repetition rate
• Arbitrary waveform generator for pulse shaping
• 0.15 – 500 ns adjustable pulse duration
• Excellent pulse energy stability
• Cost effective flash lamp pumped power amplifier
• Optional temperature stabilized harmonics options
• Super-Gaussian beam profile

Applications

• OPCPA pumping
• Front end for power amplifiers
• Ti:Sapphire pumping
• Laser peening – material hardening by laser-induced shock wave
• Plasma and shock physics

Description
The NanoFlux AWG laser system starts with a single-mode CW laser, which is amplified in a fiber amplifier. The AWG-driven modulator transmits pulses of the required temporal shape and duration, which are further amplified by a diode-pumped regenerative amplifier or an all-in-fiber amplifier to reach energies sufficient for single-pass diode and flash lamp pumped amplifiers. Pulse shaping resolution is 125 ps, with a maximum pulse length of 500 ns. The system uses linear amplifiers for high energy nanosecond pulses, with spatial beam shaping to achieve a flat top beam profile. Angle-tuned non-linear crystal harmonic generators in temperature stabilized heaters are used for second, third, and fourth harmonic generation, with a harmonic separation system ensuring high spectral purity.

Options

• – G: Provides a Gaussian-like beam profile (pulse energies typically lower by 80% compared to standard version)
• – AW: Water-air cooling option
• – N20…N500: Extended AWG pulse durations (output energies, especially for SHG output, are specified for one pulse duration with square temporal pulse shape)
