We demonstrate a chirped-pulse-amplified Ti:Sapphire laser system operating at 1 kHz, with 20 mJ pulse energy, 26 femtosecond duration (0.77 terawatt), and excellent long term carrier-envelope-phase (CEP) stability. A new vibrational damping technique is implemented to significantly reduce noise on both the stretcher compressor, thus enabling single-shot CEP value of 250 mrad RMS over hour 300 9 hours. This is, best our knowledge, ever reported for any terawatt class laser. also used pump...
Abstract For the last several decades, wavelength range accessible for strong-field, few-cycle studies has remained limited to visible, near infrared and mid-wave regimes. In particular, sources in long-wave have been lacking. We report development of a 1 kHz, laser source with up 9 μ m central gigawatt peak powers. When focused, this can ionize gas targets, which we demonstrate here through ionization atomic xenon at wavelengths ranging from 5 m. This opens new opportunities fundamental...

We generate few-cycle laser pulses from both the depleted pump and signal of an optical parametric amplifier using self-phase modulation in a single hollow-core fiber. Despite pump's poor spatial quality entering fiber, it produces field with less than 2.5 cycles. Moreover, we can simultaneously (same fiber) 4 cycle signal. The coherent combination allows for bandwidth spanning 500 to 1500 nm. geometry minimal path differences two fields, paving route generating multi-octave, synthesized...
We announce the complete genome sequences of 14 Serratia bacteriophages isolated from wastewater treatment plants. These phages define two previously undescribed types which we call Carrot-like phage cluster (phages Carrot, BigDog, LittleDog, Niamh, Opt-148, Opt-169, PhooPhighters, Rovert, Serratianator, Stoker, Swain, and Ulliraptor) Tlacuache-like (Tlacuache Opt-155).
The non-linear response of dielectrics to intense, ultrashort electric fields has been a sustained topic interest for decades with one its most important applications being femtosecond laser micro/nano-machining. More recently, renewed interests in strong field physics solids were raised the advent mid-infrared pulses, such as high-order harmonic generation, optical-field-induced currents, etc. All these processes are underpinned by photoionization (PI), namely electron transfer from valence...
An optical parametric amplifier signal and its unconverted pump are studied as a method of waveform synthesis. Generating broad spectra with self phase modulation to create coherent multi-octave CEP stabilized pulses is discussed.
We demonstrate a terawatt class Ti:Sapphire laser, 20 mJ pulse energy, 26 femtosecond duration, 1kHz repetition rate, with Carrier-envelope-phase (CEP) stabilized within 300 mrad RMS, measured single shot over 9 hours.
