    Default Coherent Compass 532-200 | 250mW+ | 33% Reserve Current | Perfect for Holography

    This is a dream laser for holography, as the the unidirectional ring cavity forces SLM operation with a coherence length exceeding 150 meters!

    This laser is a marvel of engineering. You'll be hard pressed to find another laser operating at such an ultranarrow linewidth for this price.

    I measured the output power with my Coherent FieldMax TO-II, maxing out at 299mW at the diode current limit of 3.15A

    Set to 200mW, the pump diode draws 2.1A. This leaves a very healthy reserve current of 33%.


    Free shipping to USA and Canada.

    Asking $3900 USD

    Note: The scuffed faceplate in the attachment has since been replaced with one in better condition. This laser is in quite good cosmetic condition.
