htmlText_D3E17A11_CE68_3CBD_41E3_D795755BD76D.html = New experiment in construction… More information coming soon.
Below this black curtain is the first prototype of a new product being developed by members of our teams. More information coming soon…
Inside this box, we study interactions between atom like defect spin centres in diamond and a light field inside a mechanically tunable optical micro-cavity. The micro-cavity is formed between the mirror coating at the tip of a laser machined optical fibre and a macroscopic mirror. The light matter interaction experiments in such a cavity which works at ambient conditions, helps us to explore physics that has applications ranging from quantum sensing to quantum information processing.
Genger
This is one of our big beasts: our “Gengar” laser is the workhorse of our modern optics lab: a Titanium Sapphire laser. A powerful green pump laser is sent into the aluminum boxes which contain, among other things, a cavity around a Sapphire crystal. This crystal is the heart of Gengar, it will convert the green light (532 nm) into deep red to infrared light (700 – 1020 nm), depending on our choice. We use Gengar to resonantly probe diamond defects such as the Silicon or Nitrogen vacancy defects as well as lanthanides ions like Ytterbium and Thulium doped crystals. We recently decided to use Gengar to levitate nanocrystals…
"Hulk" Laser
This is our second big beast: our “Hulk” laser. Although Hulk is of the same breed as Gengar, Hulk’s mighty power is harnessed to exert forces on micro- and nanocrystals, either to sort them out or to make them levitate.
Atomic Force Microscope (AFM)
This is an Atomic Force Microscope (AFM) combined confocal apparatus which works at ambient conditions. The apparatus enables optical imaging and size measurement of nano sized samples. We study strongly correlated quantum states using Nitrogen Vacancy colour centres in nano-diamonds for novel quantum technological applications, particularly for quantum sensing.
Bad lab practice 2:
Why is he holding scissors next to the fibres (, i.e. the yellow wires)!? What he is about to do (cutting an optical fibre) is considered high treason in an optics laboratory
Bad lab practice 3:
In the lab, although you can engage in lengthy discussions as if you were in a hairdresser salon, never oh never cut your labmates hair…
Big Red Box
This big red box and the metallic tail coming out of it is a turbomolecular pump. The pump is used to reach ultra-high vacuum, 10-7 mbar or one hundred billionth of the atmospheric pressure.
Closed-Cycle Cryostat
Here is one of our closed-cycle cryostat. This is an enhanced version of a fridge, it can go down to 4 °K (equivalent to -269 °C). The cold chamber shows several windows. We study different types of nanocrystals from room temperature to cryogenic temperatures. This includes nanodiamonds embedded
with colour centres and rare-earth ions doped nanocrystals. A cryostat is a very important tool in a quantum lab as some quantum properties only appears or are enhanced at very low temperatures. In this one, we also recently installed an optical levitation setup, using the cold chamber as a crude vacuum chamber…

Maser
This project is developing a microwave laser (maser), and exploring applications of this technology. Just as lasers (visible light) have become indispensable throughout our society, it is anticipated that masers will find equally important applications. The project makes use of defect centres in diamond, and we use optical and magnetic manipulation of the defect centres to allow the maser to function. This implementation can operate at room temperatures and is incredibly stable, unlike any previous masers created in the past.
Optical Tweezer
What you see here is a homemade optical tweezer. We optically trap nanoparticles in our homemade microfluidic chip. It allows us to study single micro- to nanoparticles in different wet environments.
Optofluidic sorter
This is our optofluidic sorter. Here we couple laser light to our microfluidic device in order to sort out nanoparticles. In the video you can see nanodiamonds being pushed by the laser.
Vacuum Chamber
This is the vacuum chamber that holds the optical levitation platform. The Ventus 1064nm laser is prepared using an array of optics and set incident onto a parabolic mirror inside the vacuum chamber. The laser is focused by the mirror and is then capable of holding up tiny particles of diamonds, silica and other dielectric materials within the region of highest laser intensity. At this point the only thing the levitated particle is interacting with is the laser field and gravity. Not only is this useful for sensing applications, it is exciting for quantum applications as we have removed many of the unwanted interactions that cause quantum states to collapse. One ongoing challenge however is to first create the quantum states out of the levitated particle’s motional dynamics.
’Bad lab practice 1:
When working in a lab you should always treat any surface (and sometimes even the floor) as the plate you will eat from, as the French say don’t ”mets les pieds dans le plats”.
LOREM IPSUM
The Arcona 340, is a 34’1” monohull sailboat designed by Stefan Qviberg. She was built by Arcona Yachts.
Arcona 340's Performances:
Upwind sail area to displacementi: 26.25
Downwind sail area to displacementi: 45.91
Displacement-Length ratio (DLR)i: 156
Ballast ratioi: 37 %
Hull speedi: 7.60 knots
Arcona 340's Auxiliary engine
Engine(s): 1
Engine type: Inboard engine
Engine: 20 HP
Fuel type: Diesel
Fuel tank capacity: 26.4 gal
Arcona 340's Accommodation
Cabin(s): 2
Berth(s) (min/max): 4 / 6
Head(s): 1
Fresh water tank capacity: 34.3 gal
Water heater capacity: 5.3 gal
Holding tank capacity: 13.2 gal
Arcona uses resin infusion to create a light, strong hull and deck comprised of multiaxial rovings and vinylester resin with a Divinycell core. A galvanized steel framework in the base of the hull carries the loads generated by the rig and keel. All bulkheads are laminated to the hull and deck. The keel is a lead bulb bolted onto an epoxy-coated cast-iron fin. The keel-stepped mast is by Seldén. Standing rigging is wire.
A nearly plumb bow and a fairly abrupt reverse transom both look sharp and maximize the boat’s sailing length. End-boom sheeting with traveler and mainsheet controls immediately forward of the helm—right where they belong—show this is a boat that means business on the racecourse.
This is quite simply a nice boat, a sailor’s boat. Its quality construction, styling and many practical seagoing design features result in a smart and make for a fast, comfortable ride underway.
