  • HiPER will use frequency tripling on the drivers.
  • Unlike most other modern ICF lasers, which are frequency tripled to the third harmonic, the GEKKO XII is only frequency doubled to 532 nm ( green light ).
  • Direct third harmonic generation ( "'THG "', also called frequency tripling ) also exists and can be used to detect an interface between materials of different excitability.
  • Nd : YAG lasers can also be used with frequency doubling or frequency tripling crystals, to produce green light with a wavelength of 532 nm or ultraviolet light at 355 nm, respectively.
  • In the same way that the bispectrum identifies contributions to a signal's skewness as a function of frequency triples, the trispectrum identifies contributions to a signal's kurtosis as a function of frequency quadruplets.
  • Research on the GDL laser at the Laboratory for Laser Energetics in 1980 first achieved efficient frequency tripling techniques which were then used next ( for the first time at LLNL ) on Shiva's successor, the Novette laser.
  • Two types of devices are currently common : " frequency doublers, " often based on lithium niobate ( LN ), lithium tantalate ( LT ), potassium titanyl phosphate ( KTP ) or lithium triborate ( LBO ), and " frequency triplers " typically made of potassium dihydrogen phosphate ( KDP ).
  • In order to avoid this problem much shorter wavelengths needed to be used, and experiments on the OMEGA laser and NOVETTE laser validated the use of frequency tripling KDP crystals to convert the laser light into the ultraviolet, a process that has been used on almost every laser-driven ICF experiment since then, including the National Ignition Facility.
  • The Nova laser as a whole was capable of delivering approximately 100 kilojoules of infrared light at 1054 nm, or 40-45 kilojoules of frequency tripled light at 351 nm ( the third harmonic of the Nd : Glass fundamental line at 1054 nm ) in a pulse duration of about 2 to 4 nanoseconds and thus was capable of producing a UV pulse in the range of 16 trillion watts.
