Traditional ultrafast oscillators required several hours to warm up and align, in order to achieve best performance. Through our vision, we are able to deliver a femtosecond laser system that doesn’t need time to warm up and doesn’t require alignment, allowing you to obtain results significantly sooner. When using the Chromacity Spark 1040 ultrafast laser as the light source within an imaging system, more time can be devoted to the imaging. This is particularly important when imaging in vivo, where samples need to be carefully prepared and conserved over specific timescales.
Pulses shorter than 100 fs suffer dispersion effects as the light travels through a microscope system. Pulses that are too long (typically longer that 300 fs), do not generate a detectable non-linear response. The Chromacity Spark laser system delivers pulse durations as short as 100 fs which make it ideally suited to all types of two-photon imaging techniques.
The high average power that the Chromacity Spark 1040 delivers (up to 2.5 W), can benefit a wide range of applications. For microscopy, the laser light can be split between more than one microscope setup. For pumping optical parametric oscillators or driving other non-linear processes (e.g. SHG, THz generation, super-continuum generation/four-wave mixing) the Spark 1040 is an ideal solution.
Our patent pending technology has been engineered into a compact footprint, making these lasers suitable, for even the smallest work environment. With a footprint the size of a sheet of A4 paper, the Spark 1040 can replace traditional ultrafast systems and free up valuable space on a lab bench.
Machined from a single block of high-grade aluminium, the Chromacity Spark has been designed specifically to deliver ultrashort pulses with an outstanding level of reliability. This has been brought about, in part, by fully integrating the pump source, and removing the need for water cooling.
An intuitive web-based user-interface allows for easy control of the Spark. This relaxes the constraints of having to be near the laser system to use it. We can provide femtosecond and picosecond variants, and alter pulse repetition frequencies depending on specific needs.
With a linearly polarized output having a beam waist of 1 mm and an M2 < 1.2, the Chromacity Spark delivers a beam quality that can be easily re-shaped and aligned into almost all microscope setups, be it research-built setups or commercially available systems.
The standard model operates at a pulse repetition frequency of 100 MHz, making it easy to integrate with a range of diagnostic equipment.
Removing the complexities of traditional ultrafast laser systems, while maintaining the high performance characteristics that are expected by the photonics industry has allowed us to develop a system that can be acquired at a low cost of ownership.
The Chromacity Spark 1040 is an ideal light source for a wide variety of industrial and scientific applications including nonlinear optics and OPO pumping, raman conversion, THz generation, multi-photon microscopy, 3-D photo-polymerisation, super-continuum generation, optical coherence tomography, Structured plane illumination (Light-sheet) microscopy and seed laser application.
