  <dc:description>HASEonGPU is open-source HPC software for calculating amplified spontaneous emission (ASE) flux in laser gain media. 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 2.0.1 is a patch release for the 2.0 series with pump-workflow fixes, Python API refinements, restored VTK pump-rate output, and updated package and publication metadata.
HASEonGPU uses alpaka 3 (https://github.com/alpaka-group/alpaka3) to support ASE calculations on CPU and GPU (CUDA, HIP) backends with improved performance portability.</dc:description>
