Abstract : A technique is presented involving a laser diode stabilized in a single mode employing active cooling at a specific current density to produce a preselected wavelength of coherent radiation. This output is used to expose for a very short time, a very sensitive holographic recording material before the diode can return to an unstable multimode, hence multilength radiation condition which would have a adverse consequences to the hologram making process.
