We used COMSOL Multiphysics to design a prototype actively cooled “flow-cell” substrate targeted at high-average-power applications, fabricated the prototype from cordierite ceramic, and tested the substrate under load in our thermal loading test

Optical parametric chirped-pulse-amplification produces two broadband pulses, a signal and an idler, that can both provide peak powers >100 GW. In most cases the signal is used, but compressing the longer-wavelength idler opens up opportunities for e

Optical parametric chirped-pulse amplification implemented using multikilojoule Nd:glass pump lasers is a promising approach for producing ultra-intense pulses (>1023 W/cm2). We report on the MTW-OPAL Laser System, an optical parametric amplifier lin

The wavefront introduced by optical parametric phase is investigated in a DKDP optical parametric amplifier by varying pump-beam amplitude and phase profiles, demonstrating their impact on the wavefront of the amplified output signal beam.

We present a theoretical and experimental analysis of the signal phase introduced by the pump-beam wavefront and spatial profile during optical parametric amplification (OPA) process. The theory predicts the appearance of an additional wavefront in t

The controlled coupling of a laser to plasma has the potential to address grand scientific challenges1–6, but many applications have limited flexibility and poor control over the laser focal volume. Here, we present an advanced focusing scheme call

The effects of pulse compressor grating misalignment on pulse duration and focusability are simulated for chirped-pulse–amplification systems of varying bandwidths, beam sizes, groove densities, and incident angles. Tilt-alignment tolerances are sp

The rapid evolutions of the electron density and temperature in a laser-produced plasma were measured using collective Thomson scattering. Unprecedented picosecond time resolution, enabled by a pulse-front-tilt compensated spectrometer, revealed a tr
