JAWS is a terawatt femtosecond chromium-doped forsterite (Cr4+:Mg2SiO4) laser system, based on an oscillator, regenerative amplifier and four stages of multi-pass amplifiers. The system can generate 80 fs pulses at 1240 nm wavelength, with pulse energies of 85 mJ giving a peak power range of 1-2 TW at 10 Hz and is assembled on a single 1.2×3.0 m optical table. Cr:forsterite is directly pumped at 1064 nm removing the need for more expensive green pump lasers. Fundamental, 2nd and 3rd harmonics of Cr:F laser are convenient for a number of applications in time-resolved spectroscopy, telecommunications, photochemistry, photobiology, plasma physics, VUV, x-ray generation, and material processing. Wavelength range is also well outside the visible and shows significantly less pulse broadening in atmosphere than 800 nm.

The Pismo pulse picker system comprises of a control and power supply unit (CPSU) and a Pockels cell with a HV driver.

The CPSU realizes the following functions: synchronization to a pulse train, amplifier pump laser start (flash-lamp or diode pumped with acoustooptical or electrooptical Q-switch) synchronously to the picked pulses, oscilloscope synchronization, streak-camera synchronization and other
equipment that requires synching to a pulse train. The CPSU has 5 independent delay channels that are rigidly fixed to a fs pulse train (jitter <200 ps). One CPSU can manage up to 4 Pockels cells. The Pockels cell consists of a HV pulse driver and an EO crystal. The HV driver produces a bell-shaped HV pulse with duration of <10 ns at level 10 % from maximum (rise/fall time <4 ns). This pulse is then supplied to the DKDP electrooptical crystal. Typical Specifications

Del Mar Photonics offers industry's most extensive portfolio of ultrafast lasers
We offer femtosecond oscillators and amplifiers based on Ti:Sapphire (Trestles, Teahupoo, Cortes), Cr:Forsterite (Mavericks, Jaws), Yb- Solid State (Tourmaline-SS), Er-doped fiber (Tamarack, Buccaneers) and Yb- doped fiber (Tourmaline). Ultrashort solid state and fiber laser sources generate coherent radiation from UV to IR for variety of applications including manufacturing of miniaturized fiber sensors, micromachining of waveguides, microfluidic devices, glass MEMS, inscription of FBG fiber Bragg gratings, stand-off detection using filament-induced breakdown spectroscopy LIBS, optical sensing, plasma generation, 3D optical fabrication, optical memory recording, generation of wide terahertz THz radiation, spectroscopy, microscopy and imaging.

Conventional microscopes have fundamentally limited resolution due to diffraction, but there is no such restriction for near-field interactions, that is why near-field microscopy is becoming important nano-science technique.
Possible applications of this tool are characterization of photonic nanodevices, bio photonics (investigation of cells, viruses, DNA molecules), nano-chemistry (chemical reactions control), nanoscale photolithography (processing of photosensitive polymers). NSOM delivered femto-second pulses can be used for nanometer-scale surface topology modification. Temporal resolution provided by femtosecond laser opens wide range of new possibilities such as: transport dynamics studies of nanostructured materials, pump-probe experiments, ultra fast coherent and Raman spectroscopy. Spatial optical resolution is better than 100 nm and temporal resolution in the pulse operation mode is better than 100 fs. Tunable CW operation for spectral measurements is also available.  Request a quote

The iPCA can be used also as large area THz detector. The two types iPCAp and iPCAs have the same active interdigital antenna area but different contact pad directions with respect to the electrical THz field.
 

Femtosecond Transient Absorption system Hatteras.

Future nanostructures and biological nanosystems will take advantage not only of the small dimensions but also of the specific way of interaction between nano-objects. The interactions of building blocks within these nanosystems will be studied and optimized on the femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar Photonics, Inc. Whether you want to create a new photovoltaic system that will efficiently convert photon energy in charge separation, or build a molecular complex that will dump photon energy into local heat to kill cancer cells, or create a new fluorescent probe for FRET microscopy, understanding of internal dynamics on femtosecond time scale is utterly important and requires new measurement techniques such as our Femtosecond Transient Absorption system Hatteras.
