Lightel’s QBH-style cable assembly for high power laser delivery provides low signal loss and excellent beam quality with power handling up to 2 kW. Our QBH-style laser heads are equipped with a safety interlock and are available in air-cooled or water-cooled versions with an anti-reflection coated quartz block to reduce power density at the output. In addition, all cables are offered with an optional integral cladding power stripper (CPS) to reduce any cladding modes due to beam reflections. The assemblies are available in standard or customer specified armored pigtail lengths and colors.
