Connecting
The Connecting section includes subsections:
■ Air-cooled connections
■ Water-cooled connections
■ Electrical connections
■ Control connections
■ DB9 connections
The Connecting section contains all the information you need to connect your Series 48 laser for opera-
tion. Figure 1-7 at the end of this chapter illustrates the connections used in a typical Series 48 laser
system.
Air-cooled connections
Note: 48-5 (50 W) lasers must be water-cooled to prevent damage to the laser. See the Water-cooled
connections section for connection details.
Since air-cooled lasers are shipped without cooling fans, customers must provide air cooling to prevent
overheating of the laser. An airflow of 250 cubic feet per minute (CFM) per fan is required to keep laser
and heatsink temperatures below 50 °C. 48-1 lasers have a heat load specification of 300 W maximum
and requires two cooling fans for a total of 500 CFM. 48-2 lasers have a 500 W heat load and requires
four cooling fans for a total air flow of 1000 CFM.
Place cooling fans symmetrically on each side of the laser so that air flow is directed perpendicular to the
laser’s cooling fins as shown in Figure 1-2. The fans should have a diameter of approximately 4.5" to 5"
and have at least 2.25" of unobstructed clearance between the outside edge of the cooling fan housing
and any enclosure or mounting surface.
