A broadband illumination source is disclosed. The broadband illumination source may include a pump source configured to generate pump illumination. The broadband illumination also includes an active medium containing nanocrystals. The broadband illumination source includes pump illumination optics configured to direct pump illumination into the active medium. The active medium is configured to emit broadband illumination by down-converting a portion of the pump illumination via photoluminescence.
