关于GLAD
The GLAD program has been developed over the last 20 years and has been applied to thousands of modeling applications. Solving hundreds of new and challenging modeling problems each year gives us the inspiration to develop new features and new examples leading to continuous improvement.
GLAD can model almost any type of laser or physical optics system with a complete end-to-end analysis, including full diffraction propagation, detailed treatment of laser gain, and many other laser effects. GLAD includes a rich range of features to handle the most difficult and complex modeling problems.

GLAD Applications |
| Everyone who works with coherent (or partially coherent) light can benefit from the program. With GLAD, the user is able to model both simple optical systems and highly complicated, multiple laser configurations. The code is designed to analyze all types of beam trains and laser devices including the effects of diffraction, active media, apertures, lenses and mirrors, and aberration. In GLAD, optical beams are represented by by complex amplitude using rectangular computer arrays. This is the most general and powerful approach. Old methods such as geometrical ray tracing, gaussian ray propagation, ABCD methods, and rotationally symmetric propagation methods can not compare in power and versatility. GLAD has been applied to a wide variety of the most advanced physical optics modeling applications including commercial laser systems, laser research experiments, stable and unstable laser design, transient laser response, photolithography, high-performance phase plates for beam control, diffraction effects, and single and multiple mode waveguides. |

GLAD is the acknowledged leader in physical optics and laser modeling. Learn to master this important field and the GLAD program in a three-day course. Instructors: Dr. George N. Lawrence, developer of GLAD. The participant will gain intuitive understanding of diffraction, optical propagation, laser gain, waveguides, and selected nonlinear optics components; learn the essentials of numerical modeling. Instruction will be by lectures on the underlying theory, in-depth discussion of numerous practical examples, and hands-on experience in solving problems in guided computer instruction sessions. This course is an introductory course in the use of GLAD to model physical optics effects when diffraction, gain, nonlinear interactions and coherence are important. This course does not assume prior experience with GLAD, but does assume some knowledge of optics and/or lasers.
