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 […]

A Very Brief Guide to Femtosecond Lasers

Lasers emit light either continuously or in a train of pulses. Under the heading of ultrafast lasers falls a certain group of lasers that produce picosecond, femtosecond or even nanosecond pulse durations at different repetition frequencies. Within this group, femtosecond lasers emit optical pulses with a pulse duration in the domain of femtoseconds (1 fs […]

An Introduction to Fluorescence Imaging

Imaging microscopic biological specimens demands greater resolution than can typically be attained via conventional microscopy. Consider a cell, which is predominantly composed of water and is subsequently transparent. Visible light-based microscopy will fail to provide much detail about cellular structures as most light on the range of 400—700 nanometres (nm) will simply transmit through. This […]

The Benefits of Dual-Comb Spectroscopy

Dual-comb spectroscopy, sometimes abbreviated to DCS, is an advanced spectroscopic technique that deploys two coherent laser sources with discrete, equally-spaced frequency lines. A laser source with this type of spectrum is defined as a frequency comb. The primary benefit of using two frequency combs is that your sample’s spectral response can be quickly assessed on […]

Continuous Wave Lasers: Understanding the Basics

Laser technology as we know it was first envisaged on a park bench in Washington in 1951, when Charles Townes thought-up the concept of microwave amplification by stimulated emission of radiation (MASER). Within ten years, this idea had germinated, yielding the first solid-state laser with a ruby gain medium. Sixty years of near non-stop development […]
