Abstract:
A color center laser capable of operating at at least two distinct frequencies, comprising:a first ionic crystal layer having a plurality of color centers each associated with a given area on said first ionic crystal layer and each operative to be excited by light at a first given predetermined wavelength; a first metal layer positioned over said ionic crystal layer; a second ionic crystal layer positioned over said first metal layer and having a plurality of color centers each associated with a given area said second ionic crystal layer and each operative to be excited by light at a second given predetermined wavelength different from said first wavelength; wherein when light of said first wavelength is incident on said laser, color centers of said first ionic crystal layer lase at a first frequency and when light of said second wavelength is incident on said laser, color centers of said second ionic crystal layer lase at a second frequency.
