Abstract Laser-plasma accelerators (LPAs) driven by picosecond-scale, kilojoule-class lasers can generate particle beams and x-ray sources that could be utilized in experiments driven by multi-kilojoule, high-energy-density science (HEDS) drivers suc

Single-shot cross-correlation of counter-propagating, short optical pulses using random quasi-phase-matching

Autor: C. Dorrer, J. L. Shaw

Publikováno v: Optics express. 30(10)

The single-shot cross-correlation of the short optical pulses generated by two laser facilities is acquired using random quasi-phase-matching of the counter-propagating beams in a disordered ferroelectric crystal. Transverse sum–frequency generatio

Single-scan ultrafast laser inscription of waveguides in IG2 for type-I and type-II operation in the mid-infrared

Autor: W. Hu, W. Gebremichael, J. Fernandes, M. Kilinc, C. Dorrer, J. Qiao

Publikováno v: Optics Express. 31:18949

We demonstrate, for the first time to our knowledge, single-scan ultrafast laser inscription and performance of mid-infrared waveguiding in IG2 chalcogenide glass in the type-I and type-II configurations. The waveguiding properties at 4550 nm are stu

Design and optimization of a high-energy optical parametric amplifier for broadband, spectrally incoherent pulses

Autor: N. Ekanayake, M. Spilatro, A. Bolognesi, S. Herman, S. Sampat, E. M. Hill, C. Dorrer

Publikováno v: Optics Express. 31:17848

Spectrally incoherent laser pulses with sufficiently large fractional bandwidth are in demand for the mitigation of laser–plasma instabilities occurring in high-energy laser–target interactions. Here, we modeled, implemented, and optimized a dual

Spectral and temporal shaping of spectrally incoherent pulses in the infrared and ultraviolet

Autor: C. Dorrer, M. Spilatro

Publikováno v: Optics express. 30(4)

Laser–plasma instabilities (LPIs) hinder the interaction of high-energy laser pulses with targets. Simulations show that broadband spectrally incoherent pulses can mitigate these instabilities. Optimizing laser operation and target interaction requ

Ultrafast-Laser-Inscribed Type-I Waveguides and Beamsplitters inside IG2 for Mid-IR Astrophotonics

Autor: W. Gebremichael, D. Oliwa, W. Hu, C. Dorrer, J. Qiao

Publikováno v: Conference on Lasers and Electro-Optics.

We present a 1 × 4 beamsplitter that is for the first time inscribed inside IG2 material by an ultrafast laser, and a comprehensive study of inscription parameters’ effect on the performance of Type-I IG2 waveguides.

Ultrafast-Laser-Inscribed Type-II Waveguides in IG2: Self-Organized Morphology and Waveguiding Properties

Autor: W. Hu, M. Kilinc, W. Gebremichael, C. Dorrer, J. Qiao

Publikováno v: Conference on Lasers and Electro-Optics.

We report the ultrafast-laser inscription of type-II waveguides in the IG2 chalcogenide glass, focusing on the self-organized morphology within the tracks and the waveguiding properties over a large range of writing parameters.
