Product Description
639nm single frequency laser laser is provided with ultra compact design and long lifetime for at least 10000 hours, which is attractive for measurement, holography, physics
experiment, etc. The power stability reach from 1% to 5% optional. The beam
diameter at the aperture is nearly 1.5mm. And the beam
divergence is nearly 1.5 mrad. The noise of amplitude is 0.5% and 1% optional. Besides extra heat sink is added for this high stability laser with frequency.
