Laser heads
General description
Continuum’s Surelite lasers use the 811U-06 head for the Surelite I, the 811U-07 head for the
Surelite II models, and a 821V-09 head for the Surelite III model. They all have a beam height of
43 mm. The head is a modular design incorporating a rod, a flashlamp and coupling medium. It
has a linear flashlamp which is in a close coupled configuration surrounded by a high brilliance
magnesium oxide diffuser. This results in a high pumping efficiency that minimizes thermal loading
and reduces power consumption. These features combine to create the excellent pumping
homogeneity required for producing high gain, superior quality beams.
Rods
The head is designed to pump Nd+3 doped YAG. The doping levels vary from 0.9 to 1.4%. The
YAG rod ends have hard dielectric antireflective coatings (AR). The rod length is 115 mm
measured along the optical axis. The diameter of the 811U-06 rod is 6 mm and the 812V-09 rod is
9 mm.
Flashlamps
The heads are pumped by linear flashlamps. The lamp has a voltage polarity that must be observed.
The flashlamp anode can be identified by a red marking on the lamp electrode whereas the cathode
has no marking. The discharge system of the flashlamp uses a negative, critically damped pulse (-1.8
kV max) with a duration of 200 microseconds full width half max (FWHM). The gas in the
flashlamp is xenon with a pressure of 1-3 atmospheres.
Cooling
Flashlamps and laser rods must be cooled by distilled, deionized water. Resistivity of distilled,
deionized cooling water should not fall below 500 k
Ω
/cm. Do not mix any chemical products with
the distilled water.
