IEEE P2065:2020 pdf download.Draft Guide for Parameter Requirements and Test Method for Industrial Fiber Laser.
This guide specifies the required parameters that should be included in an industrial fiber laser product, such as the terminology, classification, test method, for fiber laser product. The Guide is intended to be used by fiber-laser producers, laser-processing equipment integrators and end-users.
1.2 Purpose
This guide aims to help manufacturers to produce reliable industrial fiber lasers that conform to the parameter requirements suggested by this guide. Having a uniform specification will help mitigate unnecessary confusion and technical obstacles caused by different parameters by different fiber laser providers.
1.3 Word usage
The word shall indicates mandatory requirements strictly to be followed in order to conform to the standard and from which nodeviation is permitted (shall equals is required 1*2
The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required (should equals is recommended that).
The word may is used to indicate a course of action permissible within the limits of the standard (ma equals is permitted to).
The word can is used for statements of possibility and capability, whether material, physical, or causal (can equals is able to).
2. Normative references
The following referenced documents are indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.
ISO/TR 11146-3 Lasers and laser-related equipment - Test methods for laser beam widths, divergence angles and beam propagation ratios Part 3:Intrinsic and geometrical laser beam classification, propagation and details of test methods.
IEC 60825.1 2017 Safety of laser products Part 1: Equipment classification and requirements.
3. Definitions
For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary O,zljne should be consulted for terms not defined in this clause.
3.1 Fiber lasers
Lasers using a glass fiber incorporating rare earth elements as a laser medium.
3.2 Beam quality
A measure used to evaluate the beam focusing ability. In this standard, the laser beam quality is evaluated by the M2 factor, and M2 is the ratio of the product of the beam waist radius and the beam divergence angle to the product of an ideal Gaussian beam waist radius and beam divergence angle.
3.3 Beam diameter
The diameter of the circular contour in the beam cross section at which the laser power (energy) density is 1/e2of the peak maximum.[see IEC 60825.1 2017]
3.4 Pulse duration
The Full Width Half Maximum (FWHM) temporal duration of a single laser pulse from a single-shot laser or a pulsed laser with a specific repetition rate under specified operating conditions.[see IEC 60825.1 2017]
3.5 Repetition rate
The number of pulses per second emitted from a pulsed fiber laser.IEEE P2065 pdf download.
