| LASERTRAIN 4.01 - Software for Solid State Laser Performance Simulation |
DDC Technologies and 
Center
TOM present new release of the popular LaserTrain laser design program,
now also featuring passive Q-swtching option.
The LaserTrain allows simple, accurate and reliable simulations of solid state laser performance and serves as an efficient laser design tool. Simple transparent interface with graphical explanations provides instant effective operation for users without special training. The basic information on laser physics is imbedded into the program, making it simple for users even without extensive design expertise in the area of solid state lasers.
LaserTrain is intended for computational modeling of the solid state lasers dynamics, including:
- Diode pumping and non-diode laser pumping
- Laser slab or laser rod designs
- Various laser materials, including customized laser media
- End or side pumped configurations
- Active or passive Q-switches / shutters
- Free running and Q-switched operation
- CW or pulsed pumping
The LaserTrain Software computational options include:
- Possibility of precise detailed design of the laser configuration with wide set of input data, such as active media parameters, laser slab or rod dimensions, laser resonator and Q-switch parameters (see below for more input data options
- Balance equations solution for conversion of absorbed power into inversion population, gain and stored energy in materials with constant absorption: Nd:YAG, Nd:YVO4, Nd:YLF, Nd:KGW, Ho:YAG, Er:Yb:Glass
- Kinetics equations solution for conversion of stored energy into free running or Q-switched laser output energy, giant pulse shape and duration calculation, post giant pulse lasing in the point model assumption.
The software algorithm is based on solution of the system of kinetic equations by the 4th order Runge-Cutt method (Adam’s method).
The LaserTrain delivers comprehensive output data, which allows to "see" laser performance before building a hardware prototype and optimize various laser design parameters:
- Energy storage efficiency (real-time graph and data file)
- Output pulse energy and FWHM pulse duration in Q-switch mode
- Output pulse shape (real-time oscillogram and data file) including pre-lasing and post-lasing time period
- Intracavity peak intensity and fluence
- Optical Pump Efficiency-the ratio of the total power absorbed in the active medium to the total power emitted by the pump lamp or diode
Computer system minimum requirements:
Pentium III processor
Windows 98/Me; Windows 2000/XP
128M RAM
Now you can download the demo version and start your experience with LaserTrain 4.0 - a most comprehensive and yet simple and intuitive laser design software. Whether you are an experienced laser scientist or engineer, or just a college student who wants to know more about lasers and laser physics, you will enjoy using LaserTrain with its simple and convenient interface and explanatory graphics.
A Demo allows evaluation and understanding of the LaserTrain. User Help provides detailed explanations on theory and structure of the program:
