“…It uses a cylindrical Offner telescope and a pair of gratings, similar to the device demonstrated by Itatani et al. [28] , except in a double round-trip configuration to double the dispersion and reduce the beam deformation [29] . The COS design eliminates the line focus typically found on the spherical secondary mirror of a conventional Offner stretcher.…”

Optical parametric chirped-pulse amplification (OPCPA) [Dubietis et al., Opt. Commun. 88, 437 (1992)] implemented by multikilojoule Nd:glass pump lasers is a promising approach to produce ultraintense pulses (>10 23 W/cm 2 ). Technologies are being developed to upgrade the OMEGA EP Laser System with the goal to pump an optical parametric amplifier line (EP OPAL) with two of the OMEGA EP beamlines. The resulting ultraintense pulses (1.5 kJ, 20 fs, 10 24 W/cm 2 ) would be used jointly with picosecond and nanosecond pulses produced by the other two beamlines. A midscale OPAL pumped by the Multi-Terawatt (MTW) laser is being constructed to produce 7.5-J, 15-fs pulses and demonstrate scalable technologies suitable for the upgrade. MTW OPAL will share a target area with the MTW laser (50 J, 1 to 100 ps), enabling several joint-shot configurations. We report on the status of the MTW OPAL system, and the technology development required for this class of all-OPCPA laser system for ultraintense pulses.

“…A source of ultra-broadband seed pulses delivers 180-nJ pulses, centered at 910 nm, that are compressible to 13 fs and have an instrument-limited prepulse power contrast greater than 10 12 [8]. Subsequent amplification in picosecond-pumped, noncollinear optical parametric amplification (NOPA) stages maintains the high temporal contrast and boosts the signal to the millijoule range.…”

“…Interest in femtosecond (fs) pulsed, high-intensity laser facilities continues to grow as evidenced by numerous large laser projects, including the Astra Gemini and Vulcan 10PW lasers at the Rutherford Appleton Laboratory, the Scarlet laser at Ohio State, the planned construction of the Apollon Laser Facility, the extreme light infrastructure project, and the planned construction of the multiterawatt optical parametric amplifier line (MTW-OPAL) laser at the University of Rochester's Laboratory for Laser Energetics (LLE) [1][2][3][4][5]. These laser facilities are designed to explore matter interactions with ultraintense laser sources, necessitating the construction of high-energy, short-pulse lasers with ever higher peak powers.…”

“…Any coating technology pursued must be able to provide such performance over the desired substrate aperture. This work describes the development of high-laserdamage-threshold coatings for a 15 fs optical parametric chirped-pulse-amplification (OPCPA) laser system having a spectral bandwidth of 810-1010 nm using plasma-ion-assisted electron-beam evaporation [5]. The high degree of sensitivity of controlled phasecoating designs requires that the coating performance be independent of relative humidity, thereby creating a need for a densified coating process producing low-porosity films.…”
