LAS-CAD GmbH

在过去的 15 年中，LASCAD 已成为业界领先的激光腔分析和设计软件包。大量用户的反馈帮助我们积累了优化激光谐振腔设计的经验。
为此，LASCAD 提供了独特的模拟工具组合：
激光晶体热效应的热和结构有限元分析 (FEA)、
考虑热透镜、增益引导等的 ABCD 高斯光束传播、
多模和 Q 开关操作 (DMA) 的动态分析、
包括衍射、增益饱和等的 3D 波动光学光束传播代码。
将这些模块集成到一个程序包中，使 LASCAD 成为一种多功能工具，可用于模拟激光腔并解决激光工程师面临的问题。 LASCAD 特别提供了以下计算功能：
热场和光场的 3-D 非线性相互作用分析，通常称为热透镜效应，这是固态激光器设计中的关键问题之一，
效率和功率输出计算，
多模竞争、光束轮廓和光束质量建模，
Q 开关操作的脉冲形状和脉冲能量计算，
数值本征模分析，
激光腔外的光束传播。
基于激光腔内多物理场效应的定量模型，LASCAD 允许激光工程师在提交硬件之前控制和补偿谐振器设计的各个特征。

During the last 15 years LASCAD has become an industry-leading software package for LASer Cavity Analysis and Design. The feedback from a large community of users has helped us gather experience for optimizing laser resonator design.
For this purpose LASCAD provides a unique combination 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 quantitave model of the multiphysics effects in laser cavities, LASCAD allows the laser engineer to control and compensate individual features of a resonator design prior to committing hardware.
