73, Mike VE9KK. Ultrafast supercontinuum generation in gas-filled waveguides is an enabling technology for many intriguing applications ranging from attosecond metrology towards biophotonics, with the amount of spectral broadening crucially depending on the pulse dispersion of the propagating mode. After some initial set up problems caused in total by my inexperience and with the very helpful guidance provided by Albert, I joined in a recent DX event contacting a number of operators around the country and, to my happiness, in Saipan and Brazil, all on my first night with a 100 watt transceiver! the product you have subscribed to.
