    • Implementation and validation of a CubeSat laser transmitter 

      Kingsbury, R. W.; Caplan, D. O.; Cahoy, K. L. (SPIE, 2016)
      The paper presents implementation and validation results for a CubeSat-scale laser transmitter. The master oscillator power amplifier (MOPA) design produces a 1550 nm, 200mW average power optical signal through the use of ...

    • Atmospheric characterization of cold exoplanets with a 1.5-m space coronagraph 

      Maire, A. -L.; Galicher, R.; Boccaletti, A.; Baudoz, P.; Schneider, J.; e.a. (Amsterdam Netherlands: SPIE - The International Society for Optical Engineering, 2012)
      Several small space coronagraphs have been proposed to characterize cold exoplanets in reflected light. Studies have mainly focused on technical feasibility because of the huge star/planet flux ratio to achieve in the ...

    • Trapped photoelectrons during spacecraft charging in sunlight 

      Cahoy, K.; Lai, S. T. (Institute of Electrical and Electronics Engineers, 2015-09)
      For a dielectric spacecraft charging in sunlight, the potentials are different on the sunlit and dark sides. Differential charging of spacecraft surfaces can trap low-energy electrons by means of potential wells and barriers. ...
