General features and applications
Spir is dedicated to 2D energy and gain profiles calculation in rod and
slab amplifiers. Spir simulates transverse and longitudinal diode pumped
The calculation of energy deposition is based on 3D ray tracing,
Monte-Carlo method and non-sequential propagation. Spir takes into account
amplifier specification such as absorption, Fresnel reflection, reflective
coating, and Lambertian surface diffusion.
Diodes are characterized by their emission spectrum, 3D divergence, power,
spectral shift due to temperature… Batch and parametric calculation and result
used in Commod Pro.
System geometry can be built using basic optical elements such as
cylinders, planes, ellipsis, parabolas...

Windows 98 / NT / 2000 / XP/ Seven.
Spir interface is very intuitive, you get all information to build the
pumping system and visualize outputs.
