An investigation was made of the coherence of the radiation emitted by a compact cw semiconductor laser with a holographic selector, operating at room temperature. The coherence length was 20 mm for an output power of 10 mW. Holograms with a diffraction efficiency of 5.5% were recorded. The contrast in the reconstructed image was at least 10:1 and the data storage density was 104 mm2.
