Optical fiber amplifiers or fiber lasers for research laboratory

Keopsys, through interactions with universities and government-based researchers, has developed many custom optical fiber amplifiers or fiber lasers that have become standard products. Our highly educated staff continue to work with research laboratories to develop new and unique optical fiber amplifiers or fiber lasers.

Laser cooling of atoms and molecules

Keopsys has developed Erbium and Ytterbium fiber lasers, specifically designed for the laser cooling of atoms and molecules: CEFL-KILO and CYFL-KILO

The laser series performance was tailored using input from some of the leading researchers in the field of laser cooling. Keopsys manufactures this laser, with a highly rigorous quality management. Thus, these lasers are reliable and can run with an excellent output power and RIN stability.

Lasers are available at 1 and 1,5µm with a narrow linewidth (<10kHz), fine and coarse wavelength tuning, and an option for locked external frequency control. A new KILO laser is now available at 2µm.

The interaction between matter and radiated energy

« Spectroscopy is the study of the interaction between matter and radiated energy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, e.g., by a prism. Later the concept was expanded greatly to comprise any interaction with radiative energy as a function of its wavelength or frequency. 
Spectroscopic data is often represented by a spectrum, a plot of the response of interest as a function of wavelength or frequency. » http://en.wikipedia.org/wiki/Spectroscopy

Keopsys has provided many customers with tunable fiber lasers for spectroscopic applications. We offer tunable lasers and broad bandwidth optical fiber amplifiers in the wavelength regions of 1µm, 1,5µm, and 2µm. Broad tuning ranges are available in each of these regions with high output power and an excellent transverse mode.

Optical fiber amplifiers and fiber lasers tailored for your non-linear experiments

An important aspect of the study of optical non-linearity is a source that can supply high, well-defined and consistent optical intensity levels.

Keopsys lasers offer high peak power (>20kW), in Near-Gaussian shaped temporal pulses, with an excellent transverse mode beam quality. The Keopsys MOPA laser architecture permits control of peak power through either the variation of the amplifier pumps current or changes in the pulse repetition rate. In custom models, we can equip you with control of the pulse temporal width. Shot-to-shot variation is typically very low (<5%) at peak power.

The lasers are specially designed to have a narrow optical bandwidth, required for many non-linear experiments.

We also produce units that have a transform-limited output spectrum. If the customer has their own master oscillator, we can work with them to provide a power amplifier that meets their specifications.
