  1. Nanoscale Cr4+ Doped Olivine Crystallites Used In Optical Amplifiers and Lasers By: Denise Asafu-Adjei (Bronx H.S. of Science) Caesar Pereira (Archbishop Stepinac H.S.) Supervising Scientist: Prof. Petricevic (CCNY) Senior Scientist: Dr. Bykov (CCNY)

  2. Analysis of Cr doped Powders • 0.1% and 0.5% samples seem to be the optimal concentrations for laser emissions. • When heated to 1050C in general, the light emissions increased and encompassed a longer range of wavelengths. • In conclusion, we can see that because the light emissions for 1050C surpassed 1000nm, Cr4+ ions are present now in our powders.

  3. Importance of this Research • To synthesize an effective amplifying medium for the purpose of creating a “tunable laser” that will be able to emit light at multiple wavelengths • This is of significance for NASA research because these lasers would be more versatile, spatially efficient, convenient, and cost-effective

  4. Applications of Lasers • Optical communication • Remote sensing • Medical imaging • Surgery and LASIK • Tissue welding

  5. FURTHER RESEARCH • Studying the light emissions from the crystals synthesized from the powders • Attaining the optimal Cr concentration in the crystals, which will provide the maximum light emissions • In this final part of our project x-ray spectroscopy will be utilized for further analysis of our crystals that will be grown
