摘要

Point defects and their associated optical absorption bands often limit the performance of tunable laser sources (i.e., optical parametric oscillators) operating in the near and mid-infrared. Near-edge absorption in ZnGeP2 crystals and gray tracks in KTP crystals are examples of device limiting phenomena in commercially available materials, and both of these effects result from uncontrolled point defects introduced into the crystals during growth. This project identified and characterized the dominant defects in these materials. The experimental techniques employed were electron paramagnetic resonance (EPR), electron-nuclear double resonance (ENDOR) photoluminescence (PL), optical absorption, and Hall measurements. Information obtained from these studies is published and has been provided to our industrial partners where crystal growth procedures were modified in order to minimize the particular defects being identified in our spectroscopic studies. Our industrial partners were Sanders (a Lockheed Martin Company) in Nashua, NH. and Crystal Associates, Inc. in East Hanover, NJ. Specific studies included: platinum-, silicon-, and titanium- associated traps in KTP; the zinc vacancy and cation-antisite defects in ZnGeP2; and Hall measurements of CdGeAs2.
