Autocorrelator Reef RT, Del Mar Photonics, San Diego, CA
 
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.
 

Near IR viewers
High performance infrared monocular viewers are designed to observe radiation emitted by infrared sources. They can be used to observe indirect radiation of IR LED's and diode lasers, Nd:YAG, Ti:Sapphire, Cr:Forsterite, dye lasers and other laser sources. IR viewers are ideal for applications involving the alignment of infrared laser beams and of optical components in near-infrared systems. Near IR viewers sensitive to laser radiation up to 2000 nm.
The light weight, compact monocular may be used as a hand-held or facemask mounted for hands free operation.

Femtosecond Transient Absorption Measurements system Hatteras 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.

Beacon Femtosecond Optically Gated Fluorescence Kinetic Measurement System - request a quote  - pdf
Beacon together with Trestles Ti:sapphire oscillator, second and third harmonic generators. Femtosecond optical gating (FOG) method gives best temporal resolution in light-induced fluorescence lifetime measurements. The resolution is determined by a temporal width of femtosecond optical gate pulse and doesn't depend on the detector response function. Sum frequency generation (also called upconversion) in nonlinear optical crystal is used as a gating method in the Beacon femtosecond fluorescence kinetic measurement system. We offer Beacon-DX for operation together with Ti: sapphire femtosecond oscillators and Beacon-DA for operation together with femtosecond amplified pulses.
