Measuring beams coming out of a fiber
When you need to measure a beam coming out of a fiber, there are some parameters that might have a somewhat different meaning than they do when referring to "regular" beam measurements. Missing some of these points could lead to incorrect measurement, and possible equipment damage. This video clarifies some issues you'll need to keep in mind so you can set up and perform this measurement correctly.
In order to measure the fiber laser power we need to assure on one hand that the beam size on the absorber is not to small so as to exceed the power density requirements of the absorber and on the other hand that the beam size is not so large that it does not fit into the aperture. This necessitates two lengths of fiber adapter, the QBH-L & QBH-S
The QBH-L (P/N:7Z08348) is suited for beams with divergence angles of up to 120 mrad (for 86% of the beam), the minimum divergence angle depends on total power and the graph in the datasheet should be consulted for exact values.
The QBH-S (P/N:7Z08349) is suited for beams with divergence angles of up to 180 mrad (for 86% of the beam), the minimum divergence angle depends on total power and the graph in the datasheet should be consulted for exact values.
For more information please contact Ophir’s representatives.
The fiber laser outputs a very high Power and concentrated beam. If any dust or foreign particle gets onto the fiber tip, it can cause a significant damage to your fiber. The enclosure of the QBH adapter excludes foreign particles and also protects the users from back scattered laser light.
For laser powers up to 1500W use the L1500W-LP2-50 (P/N: 7Z02772) sensor or the L1500W-BB-50 (P/N: 7Z02752) sensor.
For laser powers up to 5000W use the 5000W-LP2-50 (a) (P/N: 7Z02773) sensor or the 5000W-BB-50 (P/N: 7Z02754) sensor.
Note: (a) Please note that older versions of the above sensors do not have the requisite 4 threads on Ø70mm circle on their front flange and cannot be used with the QBH adapter
