“…The development of laboratory X-ray lasers [1,2] and accelerator based 3rd and 4th generation light sources [3,4] makes coherent X-ray beams available to many researches and various applications. As for imaging and microscopy the coherence of novel X-ray sources offers several advantages and opportunities: phase retrieval technique and lensless imaging with wavelength resolution; quantitative, diffraction and interferometric microscopy; reduction of radiation loading on the investigated objects and environment and possibility to capture a diffraction pattern or an image with subpicosecond exposure prior to its degradation etc.…”

The theory of coherent reflection imaging of inclined objects at grazing angles of illumination is developed on the basis of the parabolic wave equation. A new optical transformation connecting image and object field distributions is presented. The codes for simulation the properties of practical optical systems are created. Simulation results for parameters close to an X-ray laser experiment are given.

X-ray free-electron lasers (FELs) rely on SASE due to the lack of seed lasers and the difficulty in obtaining mirrors. Progress in diamond crystal Bragg mirrors enables the design of x-ray FEL oscillators. Regenerative amplifiers (RAFELs) are high gain/low-Q oscillators that out-couple most of the optical power. An x-ray RAFEL based on the LCLS-II at SLAC using a six-mirror resonator outcoupling 90% or more through a pinhole in the first downstream mirror is analyzed using the MINERVA simulation in the undulator and OPC for the resonator. Results show substantial powers at the fundamental (3.05 keV) and 3rd harmonic (9.15 keV).

Free-electron lasers (FELs) have been designed to operate over virtually the entire electromagnetic spectrum, from microwaves through to X-rays, and in a variety of configurations, including amplifiers and oscillators. Oscillators can operate in both the low and high gain regime and are typically used to improve the spatial and temporal coherence of the light generated. We will discuss various FEL oscillators, ranging from systems with high-quality resonators combined with low-gain undulators, to systems with a low-quality resonator combined with a high-gain undulator line. The FEL gain code MINERVA and wavefront propagation code OPC are used to model the FEL interaction within the undulator and the propagation in the remainder of the oscillator, respectively. We will not only include experimental data for the various systems for comparison when available, but also present, for selected cases, how the two codes can be used to study the effect of mirror aberrations and thermal mirror deformation on FEL performance.
