Systems for Measuring Laser Outputs
Delta Developments specialises in measuring the power and energy of pulsed and CW lasers. For pulsed lasers we manufacture and supply laser peak power meters and laser energy meters. We make systems to measure the mean power, the peak power, the pulse shape and the pulse energy. All have high accuracy with traceability to UK National Standards.
Other products include a boxcar detector (= gated integrator), various amplifiers and a modulated driver for semi-conductor lasers.
Our system for measuring the peak power of a pulsed laser is probably unique. It links the peak power from a pulsed laser to the standards of CW power by using an attenuating integrating sphere together with fast photo-diodes to measure the pulse shape. Using a correctly designed integrating sphere allows the measurement of the diverging beam from the end of a fibre.

Peak Power of Laser Pulses
Measure the laser peak power , pulse shape and pulse duration
(for example, about 10W in 40ns at 10kHz from a pulsed laser diode or 1MW in 10ns from a solid-state laser)
| Pulsed Laser Energy Meters
|| Measure the laser pulse energy , pulse shape and pulse duration
(e.g. Nd:YAG laser giving 10mJ in 10ns at 1064nm)
| CW Laser Power Meters
||Measure the mean power of a laser (CW or rapidly pulsing). We offer a wide range of Laser Power Meters.
| Boxcar Integrator

| How Photo-Diodes work
|| Results of a computer model of typical Silicon photodiodes, including speed of response, linearity, effects of bias voltage and laser wavelength. Also, the relationship between CW calibration and pulsed calibration.
| Integrating Spheres
||Discusses the principles and problems of using Integrating Spheres in laser measurement systems.
| Special Developments and Consultancy
||Some examples of the sort of Development and Consultancy in electro-optics that we have undertaken in the past.
Customer Consultation . Many of our systems for laser measurement were originally made to suit the exact needs of particular customers. We can also offer expert consultation into electro-optics and optical systems across a broad range of sectors.
To complement the manufacture of our laser measurement devices we maintain our own
for laser power and energy meters. We do many calibrations of instruments from other makers as well as our own. All our calibrations are traceable to the precision standards held at the UK National Physical Laboratory ( NPL ). Typically, we achieve better than ±2% absolute accuracy. We can also make measurements on the alignment of auto-collimators, transmission of safety goggles, the attenuation of coaxial attenuators and the gain of amplifiers..
