    Laser Quantum: Looking for an efficient, high power yellow laser in a compact form factor?

    Look no further than the Laser Quantum 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 cooling systems, and a significant reduction in the effects of power loss through heat transfer. The gem range is synonymous with reliability. With long term warranty cover and global remote dial-in connection support as standard, you can be assured that a Laser Quantum product is designed for the most demanding, continuous use OEM applications.

  • Laser Quantum: Need a highly reliable laser with excellent beam qualities for Raman spectroscopy?

    Laser Quantum: Need a highly reliable laser with excellent beam qualities for Raman spectroscopy?

    The Laser Quantum 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 look at a small area/volume of a sample, you need to focus the laser to a small spot (which requires an M2 close to 1).  The ventus has a leading noise specification of <0.15% RMS, enabling a stable and consistent result in Raman spectrum: due to the weak scattering process, you want a laser that is consistent in power. As is common in Raman, customers take multiple spectra and average these, so you need your laser to be as stable as possible to make these consistent measurements, as any changes in the noise is ‘passed’ on to the final Raman spectrum​, the ventus sizably reducing this risk with its low noise. During Raman spectroscopy, having the flexibility to couple to a microscope offers ease of integration as your laser can be placed anywhere in the lab and the ventus can be free spaced coupled to a microscope. And finally, the ventus has a wavelength of 532.8 nm better than ±1 nm, making it easy to find filters to suit your set-up.

  • Laser Quantum IR cw lasers

    Laser Quantum IR cw lasers

    Infra-red (IR) lasers at 1064nm are primarily used for optical trapping, tweezing and manipulation of small particles. These techniques allow measurement and monitoring of the particles without interference from other mechanical or chemical restraining mechanisms.

    The lasers characteristics are largely driven by the sample and the objectives of the application, but high power stability and beam shape are essential. Laser Quantum offer a number of IR 1064nm lasers, all using power control feedback to ensure the high stability, and with extensive testing of beam quality, they are ideally suited to optical manipulation and many other demanding applications needing IR lasers.
