Tunable Amplified Spontaneous Emission (ASE) Laser for High Accuracy Measurement


Laser measuring instrument is widely used in different industries and applications for accurate measurement.


In many high precision systems, any minute displacement or fine movement in their structures and guidance systems will lead to undesirable results. Currently, there are very few techniques that can provide accurate monitoring and detection of minute displacements in the system. Besides, they are either very complex to implement and/or cannot be up-scaled to monitor a large establishment.


Our technology provides a simple, effective, accurate and scalable method of detecting, monitoring and measuring minute displacements and fine movements in physical spaces.




Our technology provides a tunable amplified spontaneous emission (ASE) laser source, which is comprising at least two laser sources excited by a single pump laser. It can tune multiple colour emissions from an organic laser, and such tuning can be used in laser measuring devices and systems.


In this technology, the ASE processes can be used to realize tunable emission spectra of a cascaded organic thin film system, which is consisting of blue and green emission organic semiconductors. When the cascaded films were pumped by a pulsed UV emission laser, the directional emission of ASE from the two kinds of materials can be tuned by spatially choosing the emission signals. Therefore, the system equipped with the laser source and optical sensors can be used for various measurements and monitoring.



This technology can be used in laser generating devices and laser displacement sensors. They could be the perfect tool for automatic testing and measuring of dimensions. It enables high accuracy and non-contact measurement in different industrial applications such as quality control and process monitoring.


This technology can also be used to design a polychrome light source for display, bio-imaging and related applications.



The global market for Laser Displacement Sensors is expected to grow from US$3.5 Billion in 2020, to reach US$5.3 Billion by 2027, at a CAGR of 6.2%.



It is suitable for a variety of industries and applications, including position, vibration and rotation measurements. The precision in measurement offered by our technology is not readily available in the market.
