Methods of laser pulse development and maintenance in a compact laser resonator
Described herein are methods for developing and maintaining pulses that are produced from compact resonant cavities using one or more Q-switches and maintaining the output parameters of these pulses created during repetitive pulsed operation. The deterministic control of the evolution of a Q-switched laser pulse is complicated due to dynamic laser cavity feedback effects and unpredictable environmental inputs. Laser pulse shape control in a compact laser cavity (e.g., length/speed of light <˜1 ns) is especially difficult because closed loop control becomes impossible due to causality. Because various issues cause laser output of these compact resonator cavities to drift over time, described herein are further methods for automatically maintaining those output parameters. |

Rotary anode for an X-ray source
The rotatable anode of a rotating anode X-ray source has demanding requirements placed upon it. For example, it may rotate at a frequency as high as 200 Hz. X-ray emission is stimulated by applying a large voltage to the cathode, causing electrons to collide with the focal track. The focal spot generated at the electron impact position may have a peak temperature between 2000° C. and 3000° C.

Therefore, demanding requirements are placed upon the design of the rotating anode. The present application proposes a multi-layer coating for the target region of a rotating X-ray anode which improves mechanical resilience and thermal resilience, whilst reducing the amount of expensive refractory metals required. |
