Covesion SFG crystals for laser cooling and trapping

April 19, 2017

Covesion's range of MSFG crystals are most commonly used in quantum optics systems where narrow linewidth lasers are needed to access specific atomic transitions in order to manipulate and cool atoms and ions. Cooling lasers with Watt level powers are readily achievable by using high power fibre pump lasers for sum frequency generation in MgO:PPLN.

Frequency Doubling Femtosecond Fibre Lasers

April 12, 2017

One of the most common applications of our crystals is for the generation of femtosecond pulses at around 780nm which can also be used as a low cost and compact alternative to the Ti:Sapphire laser. This is typically achieved by frequency doubling a high power 1560nm fibre source using a 1mm long MgO:PPLN crystal (MSHG1550-0.5-1) at room temperature (no PPLN crystal oven needed). Such a source can be used in microscopy systems for live-cell imaging, or terahertz time-domain spectroscopy where chemical fingerprints can be identified for homeland security applications.
