1. A plasma-based light source, comprising:

  • a pressurized chamber configured to contain an ionized gas at a pressure greater than 10 atmospheres during operation;

    a substantially continuous laser for providing a beam of laser energy within a wavelength range of up to about 2000 nm to the ionized gas within the chamber to maintain a plasma, the beam configured to maintain the plasma in an elongated form having a plasma length that is greater than that of a plasma diameter; and

    a tool optically coupled to the chamber for collecting light generated by the plasma, the generated light having wavelengths of at least than 50 nm.
