LASCAD ABCD Matrix display
LASCAD offers four interactive program modules:

ABCD Matrix (ABCD)
This is the basic LASCAD program module in which the resonator configuration and optical elements (mirrors, lenses, apertures) are entered
It analyzes the fundamental resonator mode assuming Gaussian wavefront propagation.
For non-Gaussian analysis, see Beam Propagation Method (BPM) below
Heat load in dual end-pumped rod
Finite Element Analysis (FEA)
FEA analyzes thermal and mechanical stresses in the crystal.
It then inserts a thermal lens into the cavity to compute the resonator mode, output power, and resonator stability.
FEA takes into account material parameters, pump configuration and cooling geometry.
Interactive 3D graphics show temperatures and stresses along the crystal in different planes.
Models are included for rods, slabs and thin disks.
For unique pump configurations or custom pump light distribution, LASCAD includes interfaces with ZEMAX-EE and TracePro.
eigenmodes in laser resonator
Beam Propagation Method (BPM)
BPM does a wave optics analysis without assuming parabolic wavefront propagation.
It takes into account diffraction due to the finite extension of apertures and mirrors.
BPM shows eigenmodes and simulates misalignment effects.
Q-switch pulse
Dynamic Multimode Analysis (DMA)
DMA analyzes multimode and actively Q-switched lasers.
It computes beam quality and output power in higher order modes.
For Q-switched lasers, DMA computes pulse shape and time-dependent output power.
