HASEonGPU Software - High performance Amplified Spontaneous Emission on GPU

It supports the design and analysis of high-power laser systems by estimating ASE flux in configurable gain media using a Monte Carlo ray-tracing approach. Release 2.1.1 moves pump time stepping into the compiled C++/Alpaka backend, adds compiled frozen-RK4 and ASE controls, improves streamed output handling, and separates the private Python runtime from optional public C++ installation artifacts.

HASEonGPU uses alpaka 3 (github.com/alpaka-group/alpaka3) to support ASE calculations on CPU and GPU (CUDA, HIP) backends with improved performance portability.
