    • Disclosed is a heating unit which can comprise a tube, or pipe, having an aperture therein which can be configured to receive a heating element. In various embodiments, the heating element can comprise a resistive element which can be configured to generate heat when a voltage differential is applied thereto. In certain embodiments, the heating unit can further comprise a collar which is threadably engaged with the tube, wherein a flame path, or exhaust path, can be defined between threads on the pipe and threads on the collar, for example. In certain embodiments, the flame path can comprise a passageway defined between the circumference, or perimeter, of the tube and the collar. Such a flame path can be configured to allow pressurized gasses to safely escape from the tube along a predetermined path.

    • A dye laser amplifier is formed by a stimulated brillouin scattering (SBS) dye cell which receives both dye laser light to be amplified and a pump beam along a common optical path. Phase conjugation and amplification of received energy are reflected from the SBS cell. The cell comprises an SBS medium that is a solvent for the laser dye used. Typical SBS mediums are methanol, acetone, isopropyl alcohol, etc. Typical dyes are Rhodamine 6G, Rhodamine B, Rhodamine 560, Rhodamine 575, Sulphorhodamine B, Kiton Red, DCM, Courrarun 523, etc. A plurality of amplifiers may be connected in series to provide increased amplification. The action of the phase conjugation corrects optical distorsions, thereby preserving beam quality and bandwidth even after multiple amplifications. A typical dye laser beam of 590 nm wavelength, about 1 .mu.J may be amplified to about 120 mJ, with a 17 nsec pulse width, and
