Laser Quantum Venteon Pulse OPCPA seed

The Laser Quantum Venteon PULSE OPCPA seed laser system represents the ideal front-end for broadband few-cycle OPCPA applications. The spectral bandwidth of this laser allows for the generation of broadband sub-6fs pulses as signal for a subsequent NOPA stage and provides sufficient pulse energy (>30 pJ @ 1030nm) for seeding an Yb-based amplifier pump stage. The pulses are provided by two separate output ports and are intrinsically self-synchronized with ultra-low timing jitter  

Specifications:

Wavelength 800nm (Central)
Spectral FWHM >200nm
Pulse Duration <6fs
Peak/Pulse energy >2.5nJ
Pulse/Repetition Rate 80MHz
Average Power >200mW

Additional Information:

The second output around 1030nm delivers - without any additional broadening - more than 30pJ in a spectral bandwidth of 10nm (FWHM) and is ideally suited as narrowband seed for pump amplifiers. Optionally this output can be ordered pre-amplified, delivering pulses with an energy >1nJ.

Pump-amplifier seed output:

  • Center wavelength: 1030nm
  • Spectral bandwidth: 10nm (FWHM)
  • Pulse duration: <200fs (Fourier-limited)
  • Pulse energy (free-space, 80MHz): >30pJ (>2.4 mW)
  • Pulse energy (fiber-coupled, 80MHz): >12pJ (>1 mW)
  • RMS noise (1h): <0.5%
  • FC/APC fiber port at the laser enclosure for easy seed pick-up
  • Pre-amplified for optimal amplifier seeding (optional)
  • Pulse energy (pre-amplified, fiber-coupled, 80MHz): >1nJ (>80 mW)

Next Generation THz from Toptica: Fast, compact and cost effective

TOPTICA presents new cw THz System with 1.5 µm lasers

At the recent Photonics West exhibition, TOPTICA Photonics presented the most compact frequency-domain terahertz spectrometer built to-date. The system combines TOPTICA’s new TeraBeam, a highly integrated twocolor diode laser, with newly developed InGaAs/InP emitter and detector technology (Fraunhofer Heinrich-Hertz Institute, Berlin, Germany).

The new cw THz system features a fast scan option, which reduces the acquisition times in cw THz spectroscopy by more than two orders of magnitude and acquires a complete THz spectrum (e.g. 50-1200 GHz, sub-GHz resolution) in less than a minute. Thus far, research in the field of frequency-domain (cw) terahertz has largely been carried out with GaAs photomixers, requiring laser wavelengths below 870 nm. Whilst excellent results in terms of bandwidth and signal quality have been obtained, the complexity of the optical source and a variety of non-standard optical components resulted in a price level inadequate for widespread industrial use.

Toptica TeraScan Frequency-Domain Terahertz Platform

terascan 02

  • TopSeller systems for cw-THz spectroscopy
  • Includes cutting-edge GaAs or InGaAs photomixers
  • Highest dynamic range: TeraScan 1550
  • Highest scan range: TeraScan 780
  • Digital control electronics DLC Smart

TOPTICA’s TeraScan platforms are well-established “TopSeller” configurations for frequency-domain terahertz spectroscopy. The systems combine mature DFB diode lasers with state-of-the-art GaAs or InGaAs photomixers. The TeraScan 780 offers an outstanding bandwidth, and the TeraScan 1550 sets new benchmarks in terms of terahertz power and dynamic range. Both systems feature TOPTICA's proprietary “DLC smart” control electronics.

Toptica TeraSpeed Superfast Terahertz Screening Platform

TeraSpeed 01

  • Extremely fast measurements of terahertz pulse intensities (patent pending)
  • Photoconductive terahertz emitter + high-bandwidth Schottky receiver
  • Digital output: Data rates up to 500 kS/s, “snapshot” and “continuous” measurement modes
  • Analog output: Detection of individual terahertz pulses @ 100 MHz repetition rate
  • Robust setup without any delay stages or mechanically sensitive components

The Toptica TeraSpeed serves applications in quality control and process monitoring that require no spectral information, but call for terahertz intensity measurements at “extreme” speeds: the system is capable of detecting individual terahertz pulses at repetition rates as high as 100 MHz. An integrated data-processing unit converts the detected pulses to RMS values, enabling data streams at sampling rates up to 500 kHz – orders of magnitude faster than conventional terahertz systems. Bringing together several cutting-edge technologies, the TeraSpeed takes advantage of mature fiber laser technology, powerful photoconductive emitters and fast yet sensitive Schottky receivers.

Toptica TeraFlash: Time-domain terahertz spectroscopy

Toptica TeraFlash

TOPTICA introduces the new TeraFlash system, a table-top platform for time-domain terahertz spectroscopy. The all-fibre design is based on mature 1.5 µm telecom technology, combining TOPTICA’s established femtosecond fibre lasers and state-of-the-art InGaAs antennas.

Using a highly precise delay stage, the TeraFlash achieves a peak dynamic range of more than 70 dB. Users can choose between a “precisescan” mode and a “fast scan” mode. In “precise scan” mode a bandwidth of 4 THz and a resolution better than 10 GHz are attained. Alternatively, in “fast scan” mode, a pulse trace is acquired in only 50 ms. The fibre-coupled antenna modules can be conveniently arranged, depending on the needs of the experiment. Integrated in the system is TOPTICA’s FemtoFErb 1560, the most compact ultrafast laser on the market. The SAM mode-locked fibre oscillator and the usage of polarization-maintaining fibres ensure a high robustness and alignment-free, “hands-off” operation. The TeraFlash system is a perfect solution for applications such as high-bandwidth spectroscopy (e.g. of explosives or liquid crystals) and industrial process control.

Toptica: FemtoFErb – the most compact and cost effective laser source for THz generation

FemtoFErb 780 01

TOPTICA’s new FemtoFErb is a turnkey laser system providing 100 mW average power at 1560 nm and a pulse duration of less than 150 fs at 100 MHz repetition rate. Using the same compact platform as TOPTICA’s PicoFYb, the FemtoFErb is a robust all-fiber setup based on Erbium doped fiber and saturable absorber mirror mode-locking (SAM) technology. The compact system includes all necessary control electronics and is equipped with a direct polarization maintaining fiber output interface. The FemtoFErb is an ideal solution for Time-Domain Terahertz generation or for metrology applications allowing highest accuracy laser-based distance measurements.

Also recently released: The new FemtoFiber pro UCP provides a super-continuum between 980 – 1400 nm and more than 30 mW output power. It shows pulse durations even below 25 fs, the fastest one can get on the market from a turnkey SAM modelocked fiber laser system. The system is ideally suited for biophotonics, pump-probe experiments or fs?spectroscopy. The UCP option expands TOPTICA’s successful FemtoFiber proseries and will be live demonstrated at the forthcoming Ultrafast Phenomena conference exhibition.
