Long Term Power Stability

When selecting lasers for holography and imaging applications, the coherence length of the lasers used to create the hologram is essential. The coherence length directly corresponds to the resolution of the holographic image and requires single frequency operation with excellent power stability. 

 

UniKLasers can offer these specifications at a variety of wavelengths within a small footprint. We currently offer single frequency lasers in the red and green areas of the visible spectrum with our Solo 640 Series and Duetto 532 Series respectively; and are developing a blue system to complement these and facilitate high resolution, full colour holograms.

Quantum Technology

The emerging field of quantum technology relies on accurately creating, manipulating and reading from quantum states of matter. This often requires lasers with excellent linewidth and stability to precisely manipulate the states of individual atoms, such as Rubidium or Strontium. 

UniKLasers works closely with the quantum industry to supply narrow linewidth, high power lasers at the specific wavelengths related to the exact atomic transitions they wish to target, including our Solo 780.24 QT Series for Rubidium and Solo 698.4 QT Series for Strontium. Our technology ensures excellent output power and wavelength stability during prolonged operation.

Raman spectroscopy demands the use of robust, narrow linewidth lasers with minimal spectral drift and high power stability, particularly in analyses requiring long acquisition times or high resolutions. All of our lasers are specified to ± 1 pm of spectral drift and < 2 % power variance over 8 hours of operation.

 
Our Duetto 532 Series is a popular choice for versatile Raman spectrometers, while our Solo 1064 Series is specifically well-suited to analysis of biological samples, where background fluorescence must be eliminated. Ou
r rare wavelengths, like 689 nm and 523 nm, act as enablers for some previously impossible research within this application.

Integrated Circuit - IC

Where sub-micron accuracy is required, our proprietary BraMMS Technology® ensures narrow linewidths and single frequency operation without sidebands, reducing the error in measurement.

 

We also offer short wavelengths into the UV, allowing for higher resolution surface profiling. Long-term power and wavelength stability also reduces the need for calibration corrections and removes errors when taking prolonged measurements. The Duetto 532 Series and Solo 640 Series are a popular choice for many metrology, sensing and interferometry applications.

Optical Tweezer

Optical manipulation, also known as optical tweezing or optical trapping, requires lasers with good power and pointing stability, along with excellent beam circularity. With M2 < 1.05 in both axes and the robust design of our BRaMMS technology, both our Solo 1064 Series and Solo 640 Series are ideally suited to this application.

When considering a suitable laser for flow cytometry, high power output, power stability and imperceptible power noise are vital. Excellent beam quality and pointing stability are also key parameters for ensuring consistent and accurate analysis.

UniKLasers design and manufacture single frequency lasers with unrivalled wavelength stability, narrow linewidths and long coherence lengths over a range of wavelengths within a small footprint. We currently offer lasers in the red and green areas of the visible spectrum with our Solo 640 Series and Duetto 532 Series respectively; to complement our Solo 1064 Series.

A laser source for Brillouin applications must have extremely narrow linewidth, with long coherence lengths, to ensure that the results are observed clearly. High wavelength and power stability are also vital to ensuring that Brillouin scattering, and interferometry observations in general, are not obscured by other optical effects over the time of the measurement.

 

Our Solo 640 Series, Duetto 532 Series, and Solo 1064 Series have the wavelength stability, narrow linewidth and long coherence length to suit Brillouin applications.

In Interferometry applications, high spectral stability is needed to ensure that pattern changes are caused by the sample, rather than laser effects. Longer coherence lengths and narrow linewidths will partly determine the resolution of the measurement, along with consideration of the wavelength used.​ High beam pointing stability ensures a consistent measurement on the selected sample position, whereas high beam quality reduces complexities in analysing measurements.​

For Interferometry applications, we currently offer single-frequency lasers with our Solo 640 Series, Duetto 532 Series, and Solo 1064 Series. 

The use of short range LiDAR is a growing sub-section of the Light Detection and Ranging market. Short range LiDAR is useful in making such measurements as wind speed, shear and turbulence over distances less than 500 m. This makes it extremely useful for measuring airflows over a short time scale, but with higher resolution and greater accuracy.

 

This is important in applications such as wind tunnel profiling, turbulence at airports caused by landscape anomalies, as well as air turbulence in front of a flying aircraft, and optimising wind turbine locations and performance.

In the wind turbine industry the location of windfarm placement, and indeed individual turbines, is key to maximising the efficiency of power generation. Consequently, measurements are needed that detail the wind characteristics at any point and how they are affected by the local environments, such as topography or vegetation.

 

On land this can be expensive, as high towers are erected with cup-anemometers at various heights, but at sea site surveying becomes even more difficult. Short range LiDAR systems are small and mobile, allowing them to be quickly and easily moved to different sites to assess the optimal positioning. Once in place, the short range LiDAR can be used to optimise the pitch of each turbine blade to maximise the efficiency given the approaching wind conditions.
