Request Information

Laser Quantum researches, develops and manufactures a range of CW and UF lasers and oscillators. Covering a wide wavelength, power and repetition rate range; every laser is thoroughly tested for its beam quality, robustness and is supplied with industry leading warranty periods. Our lasers are used in fundamental research in physics, super-resolution, fluorescence and two photon microscopy, optical trapping and many other laser applications.

Offering lasers across the spectrum; green, red, blue, yellow and Infra-Red (IR), manufactured to a variety of different sizes, powers and technologies, all tested for robustness and provided with long lifetime warranties.

Green lasers especially 532nm, are perhaps the most widely used wavelength of all those available. From a few tens of mW for bio-imaging, a few hundred mW for Raman spectroscopy, fluorescence imaging and holography to Watts for optical tweezing and higher powers for Ti:Sapphire oscillator pumping.

Red lasers are growing in importance, especially the 660nm and 671nm. They are especially prominent in DNA sequencing, fluorescence and Raman imaging and with the development of higher powers, super-resolution microscopy uses the red laser for de-excitation.

Blue lasers, 473nm, are often used in bio-medical imaging, neuroscience, optogenetics, Raman or fluorescence microscopy, and as such are heavily used in research labs that demand the highest of flexibility and beam quality.

Yellow lasers 561nm, are often used in bio-medical imaging and cytometry. These applications require lasers that are both reliable and robust but with flexible control and high quality beam characteristics.

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. Laser Quantum offers a number of IR 1064nm lasers, all using power control feedback to ensure high power stability, and with extensive testing of beam quality, they are ideally suited to optical manipulation and many other demanding applications needing IR lasers.

Ultrafast

The ultrafast laser range has a broad laser offering in a variety of repetition rates and pulse lengths. The various ranges meet the increasing demands for ultrafast lasers.

The MHz range meets application’s needs, offering different architectures, pulse durations and operations. The two key ranges; the gecco and venteon range offer specific characteristics. The self-starting and maintaining mechanism of the gecco is extra-cavity and takes only a press of the start button and mode locking can be achieved within 5 minutes of system start-up. The venteon range is based on ultra-short pulse durations with high spectral bandwidths.

Gigahertz repetition rates can offer many benefits over megahertz lasers in a variety of applications. Mode spacing in frequency combs have wider separation and higher powers, two photon microscopists will see equivalent image quality, but have much longer sample viability due to the lower peak power and pump-probe experiments have greater resolution. 

Few-cycle, short laser pulses have a number of advantages for researchers, with Laser Quantum’s range of short pulse lasers producing the shortest commercially available pulse duration, typically below 5fs. At a constant average power, short pulses have a higher peak power and the higher spectral bandwidth is important for spectroscopy, THz generation and OPCPA seeding application. They also benefit the study of ultrafast processes in such applications as pump-probe or time domain spectroscopy.

THz radiation is a fast growing area of research due to its non-ionising nature and transparency to many materials. Combined with time domain spectroscopy, it can provide information on the samples effect on amplitude and phase of the radiation, thereby provide more information than other spectroscopic techniques.

Amplification - Laser Quantum is capable of all the necessary technology required to realize a complete OPCPA system and proved its expertise, knowledge and competence by developing the world’s first commercial OPCPA.
