MEASUREMENT OF POWER

Our experts have experience in creating instruments to measure power in the range of 1 μW – 10 MW. The choice of primary converters on the basis of the existing technical solutions or the development of new ones is carried out at the stage of the draft design of the created test and measurement complex. Registration of the output signals of the converters is usually carried out with the help of the Recorder “Rits822”, which allows controlling the power or power density change in several points of the experiment circuit in parallel.

Power measurement using Registrar (a PRO equipment)

The radiation power measurement and monitoring of its changes during the experiment is most expedient to carry out with the help of the Signal Recorder “Rits822”. Unlike the oscilloscope, the registration and display of readings are made in natural units (W, kW, etc.). The figure on the left shows the results of registering the pulse of a solid-state laser in the free-running mode. During the pulse, 150,000 power counts were made. The impulse has a characteristic spike structure. The stretching of the image (middle plot) allows to display the pulse structure, in particular, to estimate the spacing between individual spikes. An even larger image stretching (lower graph) allows one to estimate the duration of the individual spikes (in the example given, the spike duration with a maximum power of 10 MW is 234 ns).

Smoothing the waveform

Recorder “Rits822” when displaying information makes it possible to smooth out the shape of the pulse due to the sliding averaging of the individual power counts (that is, using a convolution with a rectangular function). The diagram on the left shows the graphs of the initial pulse and smoothed out with the averaging parameter 1200 (at each point the average value of 1200 power samples taken at the given point of the region: 600 samples up to and 600 samples after this point is plotted). In fact, the smoothed graph represents a temporary change in the average power and allows us to estimate the duration of the radiation pulse at a level of 0.5 maximum (in this case, the duration is 785 μs). Attention is drawn to the change in the vertical scale in these graphs. If in the initial pulse of the maximum power of the individual spikes reaches 20 MW, then in the smoothed pulse, the average power at the maximum is about 1.5 MW.

Parallel registration capabilities

The “Rits822” recorder provides unique possibilities for conducting the parallel recording of the radiation power at various points in the experiment circuit. The upper left figure shows the time dependences of the laser radiation power recorded in 7 sections of the optical spectrum during the eight-second start-up. The lower figure shows, on two-time scales, the readings of receivers recording the time course of the radiation of five simultaneously operating impulse channels of a complex laser installation. Converters that measure the power of laser radiation.

MEASURING ENERGY

When describing the operation of a laser in a pulsed mode, the energy of the radiation pulse is, as a rule, the first indicated parameter, as if characterizing the scale of the article. Our specialists have experience in creating measuring instruments that cover the range of pulsed energy in 13 orders (from 1 μJ to 10 MJ). The choice of primary converters on the basis of the existing technical solutions or the development of new ones is carried out at the stage of the draft design of the created test and measurement complex. At the same time, the means for recording their output signals, as well as algorithms for processing (including the joint) and options for displaying the information obtained are determined. As an example, the site presents the implementation of a 7-channel energy measurement complex.

MEASUREMENT OF THE EXPENDITURE OF LASER RADIATION

Measurement of the divergence of the laser beam is based on the preliminary registration of the radiation intensity distribution over the cross-section of the beam in the far-field. Further mathematical processing of this distribution makes it possible to determine its cross sections, projections, and also a number of moments of various orders. On this basis, the angular width of the beam is determined, i.e. its divergence.
Soviet standards and relevant practice provided for two definitions of the divergence of the beam.
By intensity: the flat angle at the vertex of the cone of rotation around the optical axis, the average power.
