  • Solid state system and method for generating ultraviolet light
    Patent number: 6816520
    Abstract: Infrared laser light generated by a solid state diode pumped transform-limited Ti:Sapphire laser is converted to UV wavelengths using third and fourth harmonic generation systems. The resulting output is tunable between approximately 187 and 333 nm. The combined solid state Ti:Sapphire laser and harmonic generation system includes feedback mechanisms for improved power and wavelength stability. The system can operate at pulse repetition rates of several thousand Hertz.
