Laser beam position monitoring system for laser processing (1 software + 2 cameras)

Fig. Monitoring the position of the laser beam during laser processing.

In laser processing, the laser beam is transmitted as a collimated beam and then focused by a lens to irradiate the object. If the direction or position of the parallel beam incident on the lens changes, the position of the focusing point changes or the beam profile changes, resulting in inaccurate processing. To keep the beam direction (pointing vector) and the position of the beam center on the lens accurate, an optical system with two beam profilers is used. The position of the incoming parallel beam (e.g., the center of the beam) is measured at two locations, and precise optical axis adjustment is performed using two mirrors so that the beam is in position at both locations.

Laser beam monitoring system for laser processing (damage) testing (1 software + 4 cameras)

Fig. Measurement using multiple CCDs in a laser processing (damage) test.

“In laser processing (damage) test, it is necessary to measure the beam profile accurately at the sample position and to determine whether or not damage has occurred after irradiation. In addition, positional reproducibility during sample exchange is important because of the large number of samples to be measured. Therefore, an optical system with multiple CCDs (beam profilers) is used.(Note that LaseView can also be used for observation using a color CCD camera because it supports color image display.)”

Optical microscope system

“By simply attaching the optical tube to the CCD camera, the beam profiler can be used as a microscope. Chromatic aberration is corrected in the visible range (400 to 700nm). By using a color camera, full color display is possible, and by illuminating with LED lights, various objects such as fiber end facet can be observed.”
  • Magnification: 10x, 20x, 40x (specify magnification when ordering)
  • NA: 0.25 (10x), 0.40 (20x), 0.65 (40x)
  • Wavelength range: 400 to 700 nm
  • Working distance: 5.5 mm (10x), 1.7 mm (20x), 0.6 mm (40x)
  • Length: approx. 180 mm

Fiber end facet (20x)

Optical fiber measurement system

A laser beam with a wavelength of 975 nm emitted from the end facet of an optical fiber (FC/APC connector) was measured with a microbeam optical system. The mode field diameter is found to be about 6.4 μm. This is consistent with the specification of the optical fiber (6.6 ± 0.7 μm @ 980 nm). It can also be seen that the measured intensity distribution (white line) and the Gaussian fitting (red line) are almost identical, although the near-field pattern of the HE11 mode is slightly different due to its Bessel function. The slight difference in the aspect ratio of the beam is due to the fact that the connector is obliquely polished. It can also be seen that the beam diameter in the transverse direction is reduced by refraction at the end of the fiber. It can see that
  • there is no damage on the end facet of the optical fiber.
  • the mode field diameter of the optical fiber is known.
  • the intensity distribution is Gaussian.
  • the connector is diagonally polished.

Analysis function details

M2 beam quality analysis function

CCD カメラ配置

The procedure for setting up the optical system is shown below.

  1. Focus the laser beam using a lens with an F value (focal length/beam diameter) of about 50 to 100.
  2. Set up a ruler or optical rail so that the CCD camera can slide along the beam within ±50mm to ±150mm from the center of the beam waist.
  3. Adjust the incident light level and gain/exposure time so that the laser beam is not too strong.
解析結果の例1

The procedure for M2 beam quality analysis is shown below.

  1. Click “Open Folder” in the “File” tab and create (or specify) an empty folder to save the images.
  2. Save about 10 to 30 beam profiles on the axis of the laser beam, centered on the beam waist and ranging from ±50mm to ±150mm in front and behind. The procedure is as follows.
    • Check the beam diameter at the beam waist.
    • Move the CCD camera to a position where the beam diameter is about 5 times larger than the beam diameter at the beam waist.
    • Fix the CCD camera and adjust the light intensity and CCD exposure time to obtain a good image with low noise.
    • Click on “Save Image” in the “File” tab, enter the current CCD position in the file name text box (Please use single-byte character in China, Korea etc.), and save the image. At this time, the unit can be added after the number, such as nm, um, mm, cm, m. If the unit is omitted, the image will be processed as mm.
      Example. 30mm.tif, 100mm.tif, 150mm.tif, etc.
    • The CCD camera is moved at intervals of 2 to 10 mm, and above step 3 to step 5 are repeated. In this case, the moving intervals do not have to be equal, and the accuracy may be improved by measuring the area around the beam waist at narrower intervals.
  3. Click the “M2 Beam Quality” button in the “Batch Analysis” tab, the M2 Beam Quality Analysis window will appear, and enter the laser wavelength in nm in the text box on the upper right.
  4. Click the “Run Analysis” button to run the analysis, and if successful, the results will be displayed in the graph.

*Analysis results are displayed as beam radius.

Beam divergence angle analysis

  2. Take measurements at two or more locations and save the images in the same folder. Include the measurement location in the file name. For example, 1.5 m, 25 cm, etc.
  3. “Click the [Spread Angle] button in the [Analyze] tab. The Batch Analysis window for the beam divergence angle appears.
  4. Click the [Run Analysis] button to run the analysis, and if successful, the results will be displayed in a graph.

Analysis function of temporal beam pointing changes
