Precision Raman Spectroscopy
Raman Spectroscopy is commonly used in process monitoring and control. It is considered as an effective technique because it can be performed in-line giving non-invasive, fast measurements and unambiguous identification with suitable calibration for precise analysis. The laser requirements often needed in an in-line Raman setup requires high power, high power stability and low noise […]

What is Particle Imaging Velocimetry?
Particle imaging velocimetry is a laser optical measurement technique which is non-intrusive and is used in research and diagnostics for flow turbulence, microfluidics, spray atomization and combustion processes. Particle imaging velocity measures the entire region within the flow as its velocity is measured simultaneously. The basic principle includes photographic recording of the motion of microscopic […]
What is Raman Spectroscopy?
Raman spectroscopy is a non-destructive chemical analysis technique which offers detailed information regarding chemical structure, phase and polymorphic crystallinity, and molecular interactions. It is ideal for sample identification and quantification processes. Raman spectroscopy works by shining a monochromatic light source—usually a laser—onto a sample and detecting the scattered light. Most scattered light is at the […]
Holography & the Basics of Holographic Storage
Holography is a technique where an object is imaged in a way that, when viewed later, it appears three dimensional (3D). This is the basic method of generating holograms, which are increasingly used in a variety of fields: art, security, data storage, and so on. In this article, we will focus on the possibilities of […]
Laser Lithography: An Overview
Laser lithography is a versatile technique for the creation of microstructures such as microelectromechanical systems (MEMS) and integrated circuits. It works on the same principles as photolithography but developments in laser technologies have meant that laser-based manufacturing has become increasingly popular. Photoresists Photolithography involves the use of a photosensitive polymer applied to surface that is […]
Ultrafast Lasers from Laser Quantum
What are Ultrafast Lasers? Ultrafast lasers produce extremely short pulses of light; usually on the order of pico- or femtoseconds. Relying on techniques such as mode locking to create a train of pulses, ultrafast lasers owe their recent success to relatively new developments in photonics. These advancements in laser technology have made it possible to […]

Need a highly reliable laser with excellent beam qualities for Raman spectroscopy?
The ventus 532 is built for Raman spectroscopy applications, with an M2 close to unity allowing for a tighter focal point hence a higher intensity. Raman spectroscopy is a weak process, so you need a high intensity IR necessary to obtain a good signal. The tight focal point is also important for spatial resolution. If you want to […]
