This invention discloses an FPGA-based F-P etalon length tilt adjustment method and device. It performs layered adjustment of "X and Y direction parallelism adjustment" and "Z direction cavity fixing," relying on an FPGA to construct a two-level priority scheduling mechanism with fixed underlying hardware. Utilizing the parallel processing advantages and nanosecond-level clock determinism of FPGA hardware logic, the X and Y direction parallelism determination is fixed as the highest hardware priority. In each control iteration, the FPGA performs threshold comparison with low latency. If the parallelism does not meet the standard, the system intercepts the Z-direction cavity fixing command within a deterministic control cycle and prioritizes the leveling branch. This "software algorithm hardwareization" strategy effectively suppresses multidimensional cross-coupling oscillations. The adjusted etalon achieves the theoretical peak transmittance and spectral resolution, and the area array detector exhibits a sharp interference ring with good contrast.

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.
