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 […]

How to Choose a Raman Spectroscopy Laser

Raman spectroscopy is a non-destructive analytical technique that yields detailed information about the chemical structure, crystallinity, and phase of sample matter. It can also be used to investigate various molecular interactions based on the scattering of incident light. Lasers have proven incredibly valuable as light sources for Raman scattering due to their high intensity and […]

What is Time-Resolved Electron Microscopy?

Electron microscopy (EM) is a powerful imaging technique renowned for its outstanding spatial resolution. It surpasses the theoretical maximum resolving power of conventional microscopy by several orders of magnitude, enabling researchers to probe nanoscale structures and to resolve the chemical composition of samples with unprecedented precision. However, standard EM systems are typically unsuited to monitoring […]
