Major advances in two disciplines are responsible for optimism in fusion R&D. In optics, the harmonic frequency conversion phenomenon has been exploited to generated high-powered laser beams that have a much Shorter wavelength than was previously possible. Laser energy can now be transferred to a fusion fuel pellet more efficiently at these wavelengths. In computer modeling, the simulation of fusion reactions initiated by lasers in fuel pellets has become increasingly detailed and realistic. Other advances in the laser fusion field are discussed in terms of temperature and density conditions, collisional energy absorption, suprathermal electrons, and frequency conversion crystals.
