The trapping chamber and oven have been designed and/or built at the KVI. The Zeeman slower is also designed and built at the KVI. Check out the pictures of more then six thousand copper windings over here. The laserlight we need for the cooling and trapping of calcium is at a wavelength of 423 nm. We use a frequency doubled diode laser (Toptica). In order to get enough blue laser power we first amplify the infrared (846 nm) light in a tapered amplifier. The typical 423 nm laser intensity at moments the machine is running like it should is about 60 mW, in the future we will certainly need more. We have observed up to 75 mW of blue light with this laser system.
