This work presented the design study and implementation of new design for virtual world of diode-pumped solid-state laser systems. This work details the investigation of the use of virtual reality modeling language (VRML) to implement and construct diode-pumped solid-state laser system which can then be easily accessed over the Internet. Detailed implementation which is intuitive the navigation can be produced and these potentially have been uses, in engineering analysis for virtual laser systems and for parameters visualization. Four different laser materials were studied in general for diode-pumped solid-state laser system, all possible parameters and two approaches for diode-pumping methods, which are end pumped, and side, pumped methods. A new model were designed and implemented in virtual reality toolbox to describe the diode-pumped laser system using the data available (rod dimensions, output-coupler reflectivities, pump source wavelength and output wavelength of the laser system). From these designing models, the threshold input power, output power, optimum transmission, extraction efficiency; slope efficiency and available power were predicted. After these calculations, different system configuration of diode-pumped solid-state laser for side and end pumping methods were designed and constructed using virtual reality toolbox with varying the reflectivity of the output coupler mirror and different shapes of reflectors as a coupling component. A range of neodymium doped crystals, operating in continuous wave and in gain switched mode at 1064 nm, are compared as laser gain materials, including Nd:YAG, Nd:YVO4, Nd:SFAP, Nd:SVAP with the exception of Nd:SVAP, slope efficiencies exceeding 40% and thresholds of less than 100mW were calculated for all these lasers. We present a virtual simulation of diode-pumped solid-state lasers, these simulations serves as platform to study in details the dynamic and static parameters of the laser system from the pumping sources to the output laser power under dynamic system environments and as a training platform for diode-pumped solid-state laser systems. A model of the laser system was built and converted into an Open GL, and then ported into SIMULINK block using virtual reality toolbox in MATLAB. The equations of dynamic and static effects on the system are solved and converted to appropriate model blocks in the SIMULINK with appropriate vector dimension used to animate or effect on the virtual world. To demonstrate the principles involved and to further investigated the practical issues, a prototype has been developed. The prototype is based up on diode-pumped solid-state laser system and use data of the laser system parameters. The simulators showed a great deal of realism and have been used to simulate different laser system geometries.
