Laser System

The mass production of laser diodes for electrical appliances has been continuously reducing the cost per piece while various customary operations additionally provide wide and selective ranges of wavelengths. A proportion of those intense light emitted are visible and may be tuned to resonance with the hyperfine splitting of alkali atoms. The low cost diode lasers have granted ample opportunities for experimental atomic physics for all countries in the world no matter what the pecuniary status. The QAO lab has been developing techniques for controlling Fabry-Perot diode lasers to a stability of one part per hundred billion as required for modern AMO science. Since six to ten lasers, all work in concert at slightly different wavelengths, are needed in a typical experiment; we are now endeavoring fully automated laser-controller system to bring out the capabilities and possibilities so that they can be managed single-handedly. With a tapered-chip amplifier integrated, our lasers will be non-compromising on power, line-width and stability.
