Laser beam quality and its focusing capability are very important parameters of a laser and are usually characterized by M² factor. To measure the M² factor for a laser, it is calculated based on the difference between the product of the beam diameter and divergence, and the ideal Gaussian beam diffraction limit. The laser beam quality M2 is as below:
M2=(PI/4*LAMDA)*d0*THETA)
Where M2 is the laser beam quality M2, PI is 3.1415927, LAMDA is laser wavelength, d 0 is beam diameter, and THETA is divergence angle.
| Part number | STC-M2 |
| Detector material | Si |
| Wavelength range | 400-1100nm |
| Receiving beam diameter | 20um-9mm |
| Testing output power range | 10nW-10W(Depends on the beam diameter) |
The system comes with software. After the positions are keyed in the software, the beam diameters, beam divergence angle, and M2 will be calculated and given as shown as follows:
