Lasers in science. View of a laser fitted to an optical bench in a physics laboratory. An optical bench is long metal bar,isolated from vibrations,to which optical components are fixed. This allows the distances between components to be accurately set and measured. Such accuracy is important with lasers,where movement of any component by 1/4 of the laser's wavelength can ruin an experiment (such as in holography) | |
