Envisioning a multiplanet life solar system with high power orbital lasers (GEO or Lagrange) for uG transit with Dr. Young Bae, Founder of PTL and YK Bae Corp. Learn about advantages of Beam Laser Propulsion (BLP)  and Photon Laser Thrusters (PLT) to achieve high delta V departure to launch cargo to nearby planets Mars and Venus within a few weeks and Earth to Moon in 14-20 hours. Topics include YAG laser, active resonant optical cavity, primary and secondary mirror, first cubesat laser beam ground 2008 demo, (Yb:YAG) thin-disk gain medium and network of high reflectance lightweight mirrors, laser/solar sails, and more !
