Generation of white-light continuum
By focusing hard enough a powerful laser beam in front of a sapphire plate, self
modulation of the beam occurs that produces an important broadening of the
spectrum (continuum generation). As shown on the graph below, apart from a peak
at the fundamental wavelength at 775 nm, the spectrum is characterized by a
broad continuum extending almost down to 450 nm.

Pismo pulse picker The Pismo pulse picker systems is as a pulse gating system that lets single pulses or group of subsequent pulses from a femtosecond or picosecond pulse train pass through the system, and stops other radiation. The system is perfectly suitable for most commercial femtosecond oscillators and amplifiers. The system can pick either single pulses, shoot bursts (patterns of single pulses) or pick group of subsequent pulses (wider square-shaped HV pulse modification). HV pulse duration (i.e. gate open time) is 10 ns in the default Pismo 8/1 model, but can be customized from 3 to 1250 ns upon request or made variable. The frequency of the picked pulses starts with single shot to 1 kHz for the basic model, and goes up to 100 kHz for the most advanced one. The Pockels cell is supplied with a control unit that is capable of synching to the optical pulse train via a built-in photodetector unit, while electric trigger signal is also accepted. Two additional delay channels are available for synching of other equipment to the pulse picker operation. Moreover, USB connectivity and LabView-compatible drivers save a great deal of your time on storing and recalling presets, and setting up some automated experimental setups. One control unit is capable of driving of up to 3 Pockels cells, and this comes handy in complex setups or contrast-improving schemes. The system can also be modified to supply two HV pulses to one Pockels cell unit, making it a 2-channel pulse picker system. This may be essential for injection/ejection purposes when building a regenerative or multipass amplifier system. |

Reef femtosecond autocorrelators The autocorrelation technique is the most common method used to determine laser pulse width characteristics on a femtosecond time scale. The basic optical configuration of the autocorrelator is similar to that of an interferometer (Figure.1). An incoming pulse train is split into two beams of equal intensity. An adjustable optical delay is inserted into one of the arms. The two beams are then recombined within a nonlinear material (semiconductor) for two photon absorption (TPA). The incident pulses directly generate a nonlinear TPA photocurrent in the semiconductor, and the detection of this photocurrent as a function of interferometer optical delay between the interacting pulses yields the pulse autocorrelation function. The TPA process is polarization-independent and non-phasematched, simplifying alignment. Reef-RT autocorrelator measures laser pulse durations ranging from 20 femtoseconds to picosecond regime. It measures pulse widths from both low energy, high repetition rate oscillators and high energy, low repetition rate amplifiers. Compact control unit operates autocorrelator head and optional spectrometer through on-screen menus. Autocorrelation trace and spectrum can be displayed and analyzed on screen or downloaded to remote computer.

Trestles Fourth Harmonic Generator - request a quote Trestles FHG is designed to work with Ti:sapphire lasers, such as the Trestles Ti:sapphire laser to provide fourth harmonic generation. Trestles FHG is an affordable and easy solution to generating pulses around 200 nm. Trestles FHG is available in two versions. The first version uses the third harmonic mixed with the fundamental wavelength to produce fourth harmonic generation. This option provides the fundamental, as well as the second, third and fourth harmonics. For input of 810 nm, 1 W, 82MHz and 50 fs, output of the fourth harmonic is at 203 nm, 300-400 fs and power is 3 mW. The second option uses two separate second harmonic generation stages to produce fourth harmonic generation. With input of 810 nm, 1 W, 82 MHz and 50 fs, output of the fourth harmonic is at 210 nm, pulse width of 500 fs and power of 10 mW. The Trestles FHG from Del Mar Photonics is an easily installed solution for adding functionality to any femtosecond laser system. Extended ranges will increase capabilities for research, and specific applications such as microscopy and spectroscopy. |

Hatteras-D
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-077 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 |
