Introduction to the expert:
Dr. George Lawrence has been a pioneer in the development modeling of advanced laser projects. He is an expert in laser physics, geometrical optics and lens design, and numerical modeling. He received his PhD from the Optical Sciences Center OSC), Univ. of Arizona in 1980 with dissertation on end-to-end modeling of a CO2 laser fusion system. He returned to OSC in 1983 as an associate professor teaching and directing research in lens design, advanced lens design, and physical optics modeling. He was advisor for numerous PhD and MS students. He served on the Hubble Space Telescope Independent Review Panel in 1990.
Dr. Ying Lin received her PhD from the Univ. of Florida in 1988. Dr. Lin is fluent in both English and Chinese. She is an expert in solid state physics, quantum optics, E&M theory, and solution of differential equations. In 1990 she joined the Laboratory for Laser Energetics (LLE), Univ. of Rochester as a research physicist and published numerous papers, many with Dr. Lawrence as co-author, related to laser fusion systems including transient non-linear Raman and quantum optics effects and groundbreaking work in application of simulate annealing optimization to laser fusion optical integrators. She joined Applied Optics Research in 1999 as Chief Theoretician.
Modeling with GLAD
At Applied Optics Research we are most proud of the fact that when people asked Prof. Siegman for the best laser modeling software he referred then to Applied Optics Research and the GLAD code.
Laser Modeling Code
In 1975, Dr. Lawrence wrote the first end-to-end modeling of the first Los Alamos National Laboratory (LANL) laser fusion system for supercomputer including diffraction propagation for all steps, spatial filter to prevent back reflection and nonlinear gain. The first PC version of the code was written in 1977 on the TRS 80 with 48K memory (about 1,000,000 time less powerful than modern PC’s) having full diffraction steps in circular symmetry and a multi-Stokes Raman nonlinear optics model.
In 1985 a commercial version of the code The General Laser Analysis and Design (GLAD) code was released and continues to be the most powerful modeling tool available for advanced laser projects. GLAD has been under continuous development since it origination and has had extensive support by government, corporate, and university organizations.
Numerical methods including nonlinear optics have been highly optimized for accuracy and speed. Maximum array sizes of 32,768 x 32,768 may be used with good calculation time.
A key feature of GLAD is the simple, but powerful command language that has a rich assortment of programming features such as calculations, macros (subroutines and functions. Multiple effects may be readily included in the same command script. For example, a Customer system might include in a single system diffraction propagation, gain, various nonlinear optic effects, and reflecting boundary walls.
Documentation and Examples
The GLAD code is thoroughly documented in three volumes: command language, theoretical description, and examples. The popup Command Composer is a great aid in writing commands. Over 500 examples are provided with the code and are organized into 125 categories. No other program would be able to model more than a very small percentage of these examples.
Organization of the 3-Day Course
The Course in organized into basic and advanced features.
Basic features, discussed mostly in the first day, consist of the simple, but powerful command language, making graphics, and essential physical optics functions including diffraction propagation through any system; simple gain models and rate equation gain; modeling resonators such as stable, unstable, bow-tie, ring; and mode competition.
Advanced features are built from the same command language, so it is easy to use them and to combine multiple advanced features into a single, complex systems. Two days is not enough to address all advanced features. We can adjust the choice of advanced features according to the interests of the Course participants.
A partial list of advanced features that may be selected are: Q-switch and steady-state lasers modeling with rate equation gain approximation; coherent dipole gain and fast-response effects; resonator configurations; misalignment of resonators; dielectric waveguides and fibers; reflecting wall waveguides; atmospheric turbulence, wind shear, and blooming; optimization of physical optics systems with damped least squares using parameters or full arrays, phase retrieval, simulated annealing, reverse optimization, polarization effects, thermal distortions and thermally induced stress birefringence Green’s function method; lenslet arrays; axicons; interferometers such as point diffracting, Michelson, and Mach-Zender; beam reshaping optics; nonlinear optics effects such as doubling, OPO, Raman, SFG, etc.; ground-to-space propagation, integration of geometrical with physical optics and lens groups; partial coherence; characterizing excimer lasers with rotated gratings and Young’s double hole method; coherent injection into resonators; adaptive optics aberration correction; 3D folded systems and global coordinates; thick optics that obey the Fresnel approximation but not the Fourier approximation, high numerical aperture systems and vector diffraction; use of the “zone” command; Talbot imaging; and use and accuracy of M-squared.
