What is LaseView-LHB ?

LaseView-LHB is a laser beam profiler for large diameter and high power laser beams working on Windows systems.
Thanks to a newly-developed optical setup, it is the first product to provide measurements for both large diameter and high power laser beams. This versatile lone product offers a wide range of applications.
It works with the LaseView software, which is known for its great usability.
Equipped wih different analysis capabilities, it is a very easy-to-use beam profiler.

Comparison between LaseView-LHB and conventional products

For high power

Conventional Beam profiling measurement with high power laser needed damping system because CCD camera may be easily destroyed.
LaseView-LHB can measure as much as maximum 100 W/cm2 laser beam without additional attenuation system by using a newly designed optical system.
It simplifies optical system and prevents introducing distortion on laser beam.

For large diameter

Until now, Beam profiling measurement with large diameter has required measuring by dividing it in several parts by making handy movement on the conventional profiler.
It takes time and energy and also, divided measurement makes laser relative intensity unclear.

LaseView-LHB solves such problems and it becomes possible to make large beam profiling at one time (Figure3)

Main Analysis Functions

2 beam quality Analysis function

It is an important parameter for focus or processing, it can be easily measured with standard methods. The procedure of the optical system setting is described below:

      1. The laser beam shall be focalized through a lens with f-number (focal length/beam diameter) between ~50 to ~100.
      2. Install a ruler or an optical rail along the beam so that the CCD camera can slide in a range of ±50mm~±150mm around the beam waist.
      3. click on the “Collective analysis” of the “M2 beam quality” tab.

See the “About beam profiler” tab for more information.

Divergence angle Analysis function

Beam divergence angle is an important parameter for light propagation characteristics which can be easily measured with a standard method. Its measurement’s procedure is described below:

      1. Measurements taken at 2 or more positions shall be saved in the same folder.
      2. Click the “Divergence angle” button of “Collective analysis” tab .

In addition, as the measurements are made at different places, it is possible to evaluate the change in power and thus the propagation loss.

Beam pointing variation Analysis function

The Beam pointing stability varies with time and is an important parameter for Laser Beam stability which can be easily measured with a standard method. Beam pointing measurement procedure is described below.

      1. Use the image logging function, and save images taken at an appropriate time interval.
      2. Click the “Pointing” button.
      3. Click the “Execute analysis”.

The changes over time of X and Y coordinates of the beam centroid will be displayed in a graph.

Specification

With LaseView-LHB, the measured large diameter beam illuminates an entrance window, the light diffused from the window is recorded by a CCD camera at the rear, which allows to measure large diameters. After several experiments, by using a particular window, the direct input of high-intensity beams of more than 100 W/cm2 was made possible and we succeeded in achieving both a high resolution and a uniform sensitivity.
