Toptica: Frequency Comb basics

standard frequency comb

Frequency combs are very precise tools which are used for applications that require highest accuracy and resolution to measure the frequency of light. A frequency comb has an optical spectrum that consists of equidistant lines in the frequency domain. These lines serve as reference to measure unknown frequencies or to stabilize a laser to a certain frequency.

The discrete spectrum in the frequency domain corresponds to a regular train of ultrashort laser pulses in the time domain. This can be generated using a mode-locked laser oscillator whereas the repetition rate frep of the laser pulses corresponds to the distance between the discrete lines of the spectrum.

New from Thorlabs: Stabilized Silicon Nitride Globar Light Source: 550 nm - 15 µm


  • Globar Source for 550 nm - 15 µm
  • 4.5 W Output Power Collimated in a Ø35 mm Beam
  • Low Power Fluctuations of <0.05% within 1 Hour
  • Optical Drift: 0.01% per Hour / 0.2% per °C
  • 60 mm Cage System Compatible
  • Manual Shutter

Thorlabs' new Silicon Nitride Globar Lamp is designed to provide 4.5 W of free-space illumination over the 550 nm - 15 µm range. An internal feedback system is employed to achieve a highly stable power output (0.05% fluctuation). The high-power output is collimated into a Ø35 mm beam for free-space applications. An aluminum reflector collects light from the silicon nitride Globar element and reflects it towards the front of the housing in order to maximize the output power. The mirror alignment is factory set to maximize the output, but it can also be adjusted by the user using the three adjustment knobs on the back of the housing.

Light Conversion Geco: Scanning Auto-correlator



  • Measures pulse duration in 10 fs – 20 ps range
  • Single set of optics for 500 – 2000 nm range
  • High resolution voice coil driven delay line
  • Non‑collinear intensity and collinear interferometric autocorrelation traces
  • Onboard pulse‑analysis software for pulse duration measurements
  • Integrated controller and computer
  • Non‑dispersive polarization control
  • FROG and FTIR ready

Operation of the Light ConversionGECO autocorrelator is based on noncollinear second harmonic generation in a nonlinear crystal, producing intensity autocorrelation trace directly related to the input beam pulse duration. One arm of the fundamental pulse is delayed by means of a magnetic linear positioning stage, providing fast, reliable motion with < 0.15 fs resolution. GECO can acquire a full intensity autocorrelation trace of 10 fs to 20 ps pulses and covers the full 500 nm to 2000 nm wavelength range.

Abberior Instruments introduce DyMIN STED: Live-cell STED with Dynamic Minimum intelligent light dose management

 npc lamina teaser 1.1280x448

Abberior Instruments announce DyNIM STED: Dynamic Minimum intelligent light dose management for live cell imaging.

Key Benefits of DyMIN STED:

  • The only live-cell superresolution microscope with resolutions down to 25 nm* (*only depending on the sample) - DyMIN STED dramatically reduces the light irradiation on your sample (up to two orders of magnitude) and features the lowest light dose of all superresolution methods.
  • Resolution truly down to 25 nm - As demonstrated by separating two fluorescent point-structures being 30 nm apart.
  • Volume / time-lapse imaging with easy3D STED resolution - DyMIN STED substancially reduces photobleaching and enables long term measurements over volumes or over dozens and dozens of frames.

Gattaquant DNA nanotechnology featured in Nature

image manager product images thumbnail dna origami based super resolution for custom nanoruler

Nature recently published a Technology Feature about DNA nanotechnology including the big names of the field from Seeman to Rothemund, Shih, Douglas and many more. So we are very happy that GATTAquant – with the first commercial application of DNA origami worldwide – is mentioned amongst them, citing their CSO Max Scheible:

One popular adornment to nanostructured DNA is light-emitting materials called fluorophores. GATTAquant DNA Nanotechnologies in Braunschweig, Germany, for instance, makes nanorulers from DNA origami structures and fluorescent molecules to validate super-resolution microscopes. Super-resolution microscopy allows researchers to take images beyond the resolution limit set by the diffraction of light, but “there is no standard to measure the resolution of the system,” says Max Scheible, head of research and development at GATTAquant. “DNA nanotechnology really enabled this.”

GATTAquant attaches fluorescent molecules at precise distances on an origami structure and mounts them on glass slides. These nanoscale rulers allow researchers to verify the resolution of sub-diffraction-limit microscopes."

Art meets Science: Looking for sound with Femto

overtoon news

The Belgian artist Christoph De Boeck uses a FEMTO voltage amplifier for his acoustic installation "Golfvorm“. He reveals the inaudible sounds of stressed metal.

Ultra Acoustic Emissions are ultra high and short acoustic waves that arise when materials under stress are degrading. 

In “Golfvorm” (“Waveform”) a salt vapor corrodes a steel sheet that bends under a load. Acoustic emissions are captured, amplified in real time by FEMTO`s HVA-10M-60-F to be finally slowed down by a computer program for reproduction. As pitting corrosion progresses, acoustic bursts from microscopic cracks will pierce the silence and carry visual tension into the acoustic space.

Toptica: All wavelengths from 190nm to 0.1THz

toptica DLC TA SHG pro 400x650

With the latest product releases, TOPTICA is able to offer a complete laser wavelength coverage from deep-UV (190 nm) to terahertz radiation (0.1 THz, corresponding to 3 mm). These lasers support a multitude of applications in biophotonics & microscopy, materials & metrology and quantum technology.

Deep-UV wavelengths as small as 190 nm are now accessible with TOPTICA’s frequency-converted diode lasers. By providing essential wavelengths like 193 nm, 213 nm or 407 nm in pure cw TEM00-mode quality, the DLC TA-SHG/FHG pro (pictured above) is an ideal solution for testing and inspection or advanced material processing, e.g. lithography patterning for holographic applications. The new lasers provide the necessary power levels that are required for these applications. On top of that, they are much easier to handle at considerably lower operating costs.
