The LASCAD is an industry-leading software package for LASer Cavity Analysis and Design. The features have been incorporated based on the feedback from a large community of users. As such, it helps users in optimizing laser resonator design by a variety of simulation tools:

Thermal and Structural Finite Element Analysis (FEA) of thermal effects in laser crystals,

ABCD Gaussian Beam Propagation taking into account thermal lensing, gain guiding etc.,

Dynamic Analysis of Multimode and Q-switch operation (DMA),

3D Wave Optics Beam Propagation Code including diffraction, gain saturation etc.

Integration of these modules into one program package makes LASCAD a versatile instrument to model laser cavities, and to solve the problems laser engineers are confronted with. LASCAD especially provides the following computational capabilities:

Analysis of the 3-D nonlinear interaction of thermal and optical fields, commonly known as thermal lensing effect, which is one of the key problems in solid-state laser design,

Computation of efficiency and power output,

Modelling of multimode competition, beam profile, and beam quality,

Computation of pulse shape and pulse energy for Q-switch operation,

Numerical Eigenmode Analysis,

Beam Propagation outside the laser cavity.

Based on a quantitative model of the multi-physics effects in laser cavities, LASCAD allows the laser engineer to control and compensate individual features of a resonator design prior to committing hardware.
