1) Required equipment represents the basic minimum necessary to perform measurement, which may be sufficient for many applications.
2) In some cases it is possible to derive the pulse energy from power measurements. Where appropriate, manufacturer’s specifications (e.g.
modulation frequency and duty cycle) may be used to calculate energy from power as an alternative to measurement. Participating laboratories shall
assure that such conversion is possible and accurate. The decision shall be based on the compatibility of the power detector specifications and the
measured laser characteristics such as peak power, pulse duration, repetition frequency, etc.
Participating laboratories shall assure that any borrowed energy meters are adequate for measurement of the laser beam in all aspects, including but
not limited to: wavelength, energy, pulse duration, repetition frequency, pulse damage threshold, etc.
3) Spectral range and resolution should be adequate so that the tested laser wavelength could be measured or verified with an accuracy of 1 nm.
4) Signal generators are only necessary when the modulated output is more hazardous than the emission at the same average power. Participating
laboratories shall assure that measurements done using modulated output represent the worst case condition
5) When lenses are used, optical aberrations shall be considered for suitability. When optics are used for angle of acceptance, the properties of the
optics shall be known and deemed suitable.
6) The use of additional apertures is only necessary when the required measurement geometry cannot be assured by the appropriate arrangement of
a circular sensor of a known diameter at an adjusted measurement distance.
7) Where hazardous levels of laser radiation are accessible during testing, laboratories must comply with national and other locally applicable safety
regulations.
Note: The presence of equipment alone does not indicate a satisfactory situation. Assessors must evaluate the equipment design, calibration,
uncertainty and documentation to ensure compliance with the directions of the standard. The requirements of ISO Guide 25 regarding validation are
applicable, as the tests of this standard are not standardised tests.
