Jaws multi-terawatt Cr:forsterite laser
First available terawatt pulses at 1240 nm. We have developed 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.
Terawatt peak power is achieved by a technique known as chirped pulse amplification (CPA) where the femtosecond seed pulse is temporally stretched with a diffraction grating before being amplified. The pulse is then compressed after the amplifying stages. This design allows the Jaws multi-terawatt system to be assembled on a single 1.2×3.0 m optical table. The subsystems (oscillator, stretcher, regenerative amplifier and compressor) used in the Jaws are our standard production products. This modular approach greatly reduces the system cost and lead time when compared to other terawatt systems available. An additional advantage is that Cr:forsterite can be directly pumped at 1064 nm removing the need for more expensive frequency doubled pump lasers.
Fundamental radiation, second and third harmonics of Cr:forsterite laser are convenient for a number of applications in time-resolved spectroscopy, telecommunications, photochemistry, photobiology, plasma physics, vacuum ultraviolet, 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.

Cortes-800 40 Terawatt Laser
The new Cortes-800 amplification system provides terawatt peak power in a compact package. Seeded with our compact Trestles Ti:sapphire oscillator, the Cortes-800 consists of three chirped pulse amplification (CPA) stages that fit on a single optical table. Pulse energies of greater than 1.5 J are achieved before compression in a vacuum chamber. Active feedback and pulse shaping allows the Cortes-800 to produce extremely high contrast ratios, and sub 30 fs output pulses with peak powers greater than 40 terawatts. Fully integrated timing and control software make the Cortes- 800 a perfect tool for the study of high energy laser- matter interaction. The initial stage of the system consists of the TRESTLES-20 femtosecond oscillator pumped with a 532 nm, 6 W DPSS laser. Generated 20 fs pulses are temporally stretched with Offner triplet technology to 400 ps. To pre-correct for spectral changes incurred as pulses pass through the system, the stretched pulses pass through an acousto-optic programmable dispersive filter. The AOPDF compensates for gain narrowing and wavelength shifting in the amplification stages and for dispersion due to propagation through system components. Before insertion into the first amplification stage, a PISMO Pockels cell pulse picker is used to gate single pulses at a repetition rate of 10 Hz from the oscillator pulse train. The stretched, shaped and picked pulses are then amplified by a WEDGE-10 multi-pass amplifier, providing high contrast ratio. After the initial amplification stage the pulses pass through a spatial filter to increase the beam diameter and improve the spatial quality of the beam. A second PISMO Pockels cell is used to increase the temporal contrast ratio and to protect STAGE-1 from back reflections. The spatially expanded pulses pass through STAGE-2, a 5-pass multi-pass amplifier. Another spatial filter is used to clean the beam before the final amplifying stage, STAGE- 3. The 4-pass power amplifier increases the pulse energy to 1,500 mJ per pulse. Pulse compression takes place within a sealed vacuum chamber with a dielectric grating compressor. Grating position, and thus final pulse duration, are adjusted with the help of computer controlled motorized stages. A deformable mirror (DM) coupled with a Shack-Hartmann wavefront sensor is used to correct wavefront distortions, resulting in a 0.8 Strehl ratio.

femtosecond transient absorption data acquisition system
Future nanostructures and biological nanosystems will take advantage not only of the small dimensions of the objects but 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. Thus we put a lot of our efforts and resources into the development of new Ultrafast Dynamics Tools such as our Femtosecond Transient Absorption Measurements system Hatteras. 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 advanced measurement techniques.

Frequency-stabilized CW single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong Kong.
DYE-SF-077 features exceptionally narrow generation line width, which amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation line width of commercial lasers. Prior to this model, the narrowest line-width of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an acousto-optical modulator, which, as a rule, complicates the design and introduces additional losses. A specially designed ultra-fast PZT is used for efficient suppression of radiation frequency fluctuations in a broad frequency range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules, Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution spectroscopy
