Looking for an efficient, high power yellow laser in a compact form factor?
Look no further than the gem 561 1 W – market leading power with an ultra-precise TEM00 beam specification, allowing for uniform energy distribution or tight focus at this key wavelength for single molecule localisation microscopy. gems novel power delivery architecture and innovative wall plug efficiency delivers two additional benefits – the elimination of complex […]
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 […]
Localization Microscopy
Read the recently published microscopy article published in Wiley Online, PhotonicsViews. The article focuses on localization microscopy, and how high–power continuous wave lasers can be used in super-resolution microscopy. Super-resolution microscopy overcomes the Abbe diffraction barrier allowing resolution greater than 200-300 nm. The article details the principles of single-molecule localization microscopy (SMLM), and how it enables improved resolution by […]
4 Tips to Achieve High-Quality Imaging in Microscopy Applications
Microscopy is an important technique across many disciplines both in research and commercially. There are many techniques used in microscopy including, spanning confocal, lattice light sheet and multiphoton—and for all, image resolution is a key factor. Resolution plays a big role in microscopy’s success as it refers to the microscope’s ability to select detail in […]
Terahertz Cyclotron Resonance Spectrometer
Dr. Darren Graham tells us about the development of the terahertz cyclotron resonance spectrometer at the Photon Science Institute, University of Manchester. Cyclotron resonance has been about since the 1960’s and the technique has led to the development of new semiconductor materials, producing light-emitting diodes and transistors. In order to perform the techniques, you need […]
A technique to achieve high resolution and faster sampling in Microscopy
Fluorescence microscopy is a continually developing tool for imaging biological samples, however, the same challenges are faced throughout the microscopy world: High-resolution levels Faster sampling rates Light-sheet microscopy is a technique that employs scanning a sample as a plane of laser light, a second excitation lens is placed on a perpendicular axis to the detection […]
Latest PLIM research released
In a recent scientific paper published in the Journal of Innovative Optical Health Sciences by The Core Imaging Facility at the University of Ulm, the use of fast repetition rate fs pulsed lasers is investigated to advance PLIM (phosphorescence lifetime imaging) microscopy. PLIM is traditionally carried out with 80 MHz Ti:Sapphire lasers, however this paper […]
Ultra-low noise
Visit the axiom 532 web page to view the detailed specifications of the newest ultra-low noise laser from Laser Quantum. The axiom 532 lends itself to Ti:Sapphire pumping as the pump laser noise is transferred directly to the noise of the Ti:Sapphire laser. When the typical noise value is <0.02% RMS, this factor is greatly […]
Using resonance scanners and ultrafast laser in FT-CARS
In this published paper by Hashimoto et al. (2018), ‘Ultra-broadband rapid-scan Fourier-transform CARS spectroscopy with sub-10-fs optical pulses’ leverages the benefits of products from Novanta. The experimental set-up contains a venteon ultra from Laser Quantum and a resonant scanner, CRS12 kHz, from Cambridge Technology. The paper demonstrates ultra-broadband Fourier-Transform Coherent Anti-Stokes Raman Scattering (FT-CARS) spectroscopy. […]
Advancements in nanoparticles
A recent paper in nature communications by Kim et al, (2018) ‘Photonic crystal cavities from hexagonal boron nitride’ uses the gem 532 laser as the excitation laser for the broadband emission in hexagonal boron nitride and single emitters. The paper examines the development of a scalable quantum photonic technique. It utilises hexagonal boron nitride as […]
