         New Products             Measurement of Laser Beam Profile and Propagation Characteristics


Laser beam profiling plays an important role in such applications as laser welding, laser focusing, and laser free-space communications. In these applications, laser profiling enables to capture the data needed to evaluate the change in the beam width and determine the details of the instantaneous beam shape, allowing manufacturers to evaluate the position of hot spots in the center of the beam and the changes in the beam’s shape.


Digital wavefront cameras (DWC) with software can be used for measuring laser beam propagation parameters and wavefronts in pulsed and continuous modes, for lasers operating at visible to far-infrared wavelengths:

- beam propagation ratio M²;

- width of the laser beam at waist w0;

- laser beam divergence angle θx, θy;

- waist location z-z0;

- Rayleigh range zRx, zRy;

- Ellipticity;

- PSF;

- Wavefront;

- Zernike aberration modes.


These parameters allow:

- controlling power density of your laser;

- controlling beam size, shape, uniformity, focus point and divergence;

- aligning delivery optics;

- aligning laser devices to lenses;

- tuning laser amplifiers.


Accurate knowledge of these parameters can strongly affect the laser performance for your application, as they highlight problems in laser beams and what corrections need to be taken to get it right.


Beam Propagation Parameters


M², or Beam Propagation Ratio, is a value that indicates how close a laser beam is to being a single mode TEM00 beam. This in turn relates to how small a spot a laser can be focused. For a laser beam propagating through space, the equation for the divergence, Θ, of a pure Gaussian TEM00 unfocused beam is given by:

Θ00 = 4λ/πD00                                 (1)

where D00 is the waist diameter of the beam, and λ is the wavelength. Actual beams with additional modes often start with a larger beam waist, D0, and/or have a faster divergence Θ0. In this case Equation (1) becomes:

Θ0 = M2 4λ/πD0                               (2)

where Θ0 and D0 are the divergence and width of a higher mode beam and M² is greater than 1 and is named the “Beam Propagation Ratio” per the ISO 11146 standard. When a pure Gaussian laser beam is focused, the diameter of the focused spot is defined by:

d00 = 4λf /πD00                                 (3)

where D00 is the ideal focused spot diameter,  f is the focal length of the lens, and is placed one focal length from the lens as shown in the Figure 1. However, when a distorted or multimode beam is focused, Equation (3) becomes:

d0 = M2 4λf  / πD0                                (4)

Apart from M², the measured beam propagation parameters characterizing laser beams are:

w0 = d0/2– the waist radius in X (horizontal) and Y (vertical) directions;

z-z0 – the distance between measurement and waist planes;

zR – the Rayleigh range, for which the radius of curvature R of the wavefront is minimal;

θ – the divergence angle of the measured laser beam far from the waist;

     R – the radius of curvature of the wavefront in the measurement plane.


STPV Series All-in-One Laser Beam Analyzers

High Resolution CCD Beam Profiler

Instant Beam Propagation & Wavefront Analysis

One Shot M2 Measurement


The smart all-in-one compact digital wavefront camera (DWC) beam profiler performs beam propagation analysis in one shot.


Thanks to its capability to measure simultaneously intensity and phase data at ultra high resolution, beam shape and intensity distribution can be measured at any distance from its original location without moving parts. All critical parameters for laser beam monitoring such as energy distribution and beam propagation parameters can be measured without need of purchasing additional tools.


DWC combined with laser beam measurement software provides comprehensive one-shot measurements of the laser beam: beam propagation parameters such as M², divergence, tilt, energy characteristics in any XY plane.


Users can make necessary adjustments in real time by visualizing the beam along the Z propagation axis, graph of waist, 2D/3D intensity profiles can be easily extracted by selecting a Z position with a slider.



Propagation parameters are measured by DWC on real beams by focusing the beam with a fixed position lens of known focal length, and then measuring the characteristics of the artificially created beam waist and divergence.


Measurement of the beam propagation parameters with DWC is based on the simultaneous measurement of the high-resolution images of intensity and wavefront. The wavefront is computed starting from two slightly defocused beam intensity images acquired on one CCD camera inside DWC by mathematical computations involving the two images and the difference between them (Figure 2). From the wavefront, the beam propagation parameters are obtained by straightforward but tedious computations.

Typical Applications


1. Laser Beam & Wavefront Profiling


Featuring resolution of 250 000 measurement points, high dynamic range (± 1500 λ of wave tilt at 633 nm), and real time wavefront analysis at 25Hz video frame rate, DWC is an ideal tool for laser beam analysis.


Multiple views of the reconstructed high resolution wavefront, containing 3D plot, wavefront gradient, fringes display are output in real time.


For laser beam measurement, the technique uses Digital Wavefront Sensor to obtain high-resolution intensity and wavefront images of the propagating beam at one location on a 1M pixel CCD array camera. From the one-shot intensity and phase measurements and numeric propagation the laser beam is obtained at >10 positions. The instrument is suitable for measurement of both CW and pulsed lasers down to single-shot rates, and provides quantitative measurement of numerous beam spatial characteristics in accordance with the ISO 13694 standard and M2 parameters according to the ISO 11146 standard. Beam diameters are obtained with accuracy to better than 2% that translates to M2 measurements with accuracy to better than 4%.


2. Beam Propagation Analysis


DWC is a one shot device offering detailed beam propagation analysis in a range up to several Rayleigh distances in the beam propagation direction.


Without displacing the device, the beam's energy - related characteristics such as beam celtroid and peak locations, and peak fluences can be precisely and quickly computed by purely numerical procedures, in a desired number of planes around the position of DWC.


The quality of the laser beam and the visualization of its hot spots can be monitored with no operator intervention over large distances around the laser beam waist.


3. Beam shaping & beam monitoring


DWC can be used for precise beam monitoring & beam shaping - both in intensity and in phase - made e.g. by phase spatial light modulators (SLM's), deformable mirrors (DM's) and other beam shaping and beam forming devices.


DWC is used e.g. to control of the adjustment of beam shaping modules to generate round and square top hat focal spots, offering ultimate resolution, speed and dynamic range.
