FAQ

Can I measure position and size of a pulsed laser using a BeamTrack sensor?

Position and Size are measured along with power. Therefore, if the laser is pulsing at a rate at which average power can be measured, then position and size can be measured as well.

When using a BeamTrack sensor with StarLab on a PC, can I have StarLab log Position and Size data? At what sampling rate?

Yes StarLab can log beam position. The BeamTrack sensors are thermal sensors. The power measurements for all Ophir power sensors are logged at 15 times a second. When a BeamTrack sensor is connected to StarLab via a Juno, the position / size measurements are also logged 15 times a second. When a BeamTrack sensor is connected to StarLab via a Vega/ Nova II, the position / size measurements are logged once a second. This is because in the Vega / Nova II we sample these parameters slower.

For what type of laser spots can we measure position and size with BeamTrack sensors?

Position can be measured for any beam shape. Size can be measured to specified accuracy only for Gaussian (TEM00) beams. For other laser modes, size measurement is relative only.

What meters support the BeamTrack (PPS) sensors?

The Vega, Nova II, StarLite. StarBright and Juno support the BeamTrack (PPS) sensors. All other instruments can display power and single-shot energy of a BeamTrack sensor, but do not display beam position and size.

Do I need to recalibrate my instrument? How often must it be recalibrated?

Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.

When using a BeamTrack sensor, is the response time for Position and Size measurements the same as it is for Power measurements?

The specified response time is only for the power and not for the size or position; response time is intentionally given in the Power section of the spec.
We haven't defined a position and size measurement response time because it depends on too many different parameters. For example:

  • Small changes in size or position will respond quickly, large changes are much slower.
  • Going from a large spot size to a smaller one is faster than going the other way.
  • Position and size can change at the same time.
  • If the power also changes it is even more complicated.

So the response time for size and position cannot be meaningfully specified by a single number. Having said all that, however: 
In general, unlike the power reading which is accelerated by the predictive “speedup” function, the size and position measurements can't use the speedup so they are a bit slower.

The rise time for Position and Size is typically 5x – 10x the specified power response time.

Fall times for a decrease in power density (i.e. increase in size relative to power, as above) can be longer.

Can I use my BeamTrack Sensor with a Pulsed Laser?

The answer to this is, of course, it depends. It depends on the pulse frequency and it depends on which sensor you want to use. Thermopile detectors do not have very fast response times, so frequencies above 100Hz are effectively the same as CW to them and all BeamTrack functions will perform as expected. Below 100 Hz the response time of the detectors becomes relevant. Low power sensors generally have faster response times so they will be more susceptible to fluctuating readings when used with a pulsed laser. The position measurement function uses the same thermopile detector as the power reading. If the laser frequency is high enough for the sensor to provide a stable power reading without fluctuations then the position measurement function will perform well too. All of our BeamTrack sensors will provide reliable position measurements for pulse frequencies down to below 10 Hz. The beam size function employs a detector that has a faster response time. At low frequencies the size measurement reading will fluctuate. We don't recommend relying on the size reading for laser pulse frequencies below 100 Hz. In any event, you can always try the sensor with your laser. If the readings are stable, without significant fluctuations, then they will be reliable.

Laser Power Sensors introduction

As described in the general introduction, the thermopile sensor has a series of bimetallic junctions. A temperature difference between any two junctions causes a voltage to be formed between the two junctions. Since the junctions are in series and the «hot» junctions are always on the inner, hotter side, and the «cold» junctions are on the outer, cooler side, radial heat flow on the disc causes a voltage proportional to the power input. Laser power impinges on the center of the thermopile sensor disk (on the reverse side of the thermopile), flows radially and is cooled on the periphery. The array of thermocouples measures the temperature gradient, which is proportional to the incident or absorbed power. In principle, the reading is not dependent on the ambient temperature since only the temperature difference affects the voltage generated and the voltage difference depends only on the heat flow, not on the ambient temperature.

Laser Measurements in Materials Processing: How and When They Absolutely, Positively Must Be Made

19th century British physicist and engineer William Thomson, 1st Baron Kelvin, was the first to say, “If you can’t measure it, you can’t improve it.” When applying this principle to improving laser-based processes, there are a variety of parameters that must be measured. Given the continuously rising power of laser systems in material processing, the requirements for measurement systems are more challenging than ever. Which technologies are available to measure high-power lasers? How often should they be measured? What measurements should be tracked? When this data is collected, what should be done with it? Read more...

How do I know what range, or scale, to set my power/energy meter to? And what happens if I go over range?

Each given range represents one level of gain of an internal amplifier. The electronics, as always, have a limited Dynamic Range. If the measured signal is too low, in other words near the bottom of the range, then it may be lost in the noise and the reading will be inaccurate and noisy. If it’s too high – there may be saturation issues. To give an instrument a usefully wide dynamic range, multiple scales or ranges are used. Switching from range to range can be automatic (“Autorange”), or manual. Autoranging simply starts automatically at the least sensitive range and works its way down the ranges, sampling the signal as it goes, till it finds a range at which the signal is properly detected. Note, by the way, that only in POWER mode is Autoranging available. If we are working in Single Shot Energy mode, there is no Autoranging – simply because when we are measuring a single pulse, the instrument has no opportunity to work its way down the ranges as in Power mode.

Types of power / Energy Laser Sensors General Introduction

Power and Single Shot Energy Sensors
Ophir provides two types of power sensors: Photodiode sensors and Thermal sensors. Photodiode sensors are used for low powers from picowatts up to hundreds of milliwatts and as high as 3W. Thermal sensors are for use from fractions of a milliwatt up to thousands of watts.
Thermal sensors can also measure single shot energy at pulse rates not exceeding one pulse every ~5s.

Repetitive Pulse Energy Sensors
For higher pulse rates, Ophir has pyroelectric energy sensors able to measure pulse rates up to tens of KHz. These are described in the energy sensor section, section 1.3.
