SANTA CLARA, Calif., Jan. 31, 2008 -- Coherent Inc. said its new Mantis is the first ultrafast laser system to incorporate a 5-W green pump laser based on monolithic OPSL (optically pumped semiconductor laser) technology rather than a traditional DPSS (diode-pumped solid-state) pump.

Mantis is a cost-effective oscillator for short pulse (broadband) ultrafast applications and has been optimized for a single operating point (in terms of wavelength and bandwidth) enabling simplified design, increased ease of use and a cost-performance benefit, Coherent said.

CoherentMantis.jpgMantis generates over 300 milliwatts of average power at a nominal center wavelength of 800 nm and has a bandwidth over 70 nm, which can be compressed to under 20 femtoseconds (fs) using the optional external CPC (compact pulse compressor). The OPSL technology used in Mantis has been widely used for several years in OEM applications such as bioinstrumentation, Coherent said.

A major application for the Mantis is seeding short-pulse amplifier/optoelectronic-pulse amplifier systems to generate tunable high energy, sub-35 fs pulses for a wide range of pulse-probe experiments in physics and chemistry, the company said. Typical examples include studies into molecular photodissociation dynamics and power-hungry techniques such as fluorescence upconversion.

In terahertz (THz) spectroscopy and imaging the Mantis oscillator will generate a wider spectrum of THz radiation because of the laser's very short pulse width, Coherent said.

GLOSSARY
broadband
Indicating a capability to deal with a relatively wide spectral bandwidth.
fluorescence
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
