Gas Purge connector (f201/f400 models only)
A gas purge is highly recommended when operating the laser in dirty or dusty environments. Purging the
laser creates a positive pressure inside the laser housing that prevents dirt and debris from accumulating on
optical surfaces including beam combiner, telescope, and turning optics. In condensing atmospheres, a gas
purge helps to reduce the potential for condensation damage.
To connect the Firestar f201 or f400 gas purge port, perform the steps described below:
1 Connect nitrogen or breathing-grade air to the Gas Purge connector using 1/4-inch plastic tubing.
2 Push the tubing completely into the tting and then pull the tubing lightly to ensure that it is locked
into place.
Note: To disconnect gas purge tubing, rst push and hold the tubing slightly into the tting. Next push
the white tting ring evenly towards the tting, and then pull the tubing free.
Caution
possible
equipment
damage
Do not exceed a gas purge pressure of 34.5 kPa (5 PSI). Excessive
pressure may damage the purge assembly or other internal laser com-
ponents.
Do not use argon as a purge gas. Use only nitrogen or clean, dry air as
described in Table 1-6, Purge gas specications.
3 Set a purge pressure between 13.8–34.5 kPa (2–5 PSI). This provides just enough positive airow
to prevent dust from entering the laser. If a owmeter is available, set a ow rate of 0.85–1.7 m

(30–60 SCFH, Standard Cubic Feet per Hour) at a pressure not to exceed 34.5 kPa (5 PSI).
The Gas Purge connector on your f201/f400 laser must be connected to a source of nitrogen or clean, dry
air only; do not use any other gases for purging. Purge gas specications are listed in Table 1-6 below.
