    a second Chaffee explained that while interest in using lasers for wireless telecommunications began in the 1960s continuous wave lasers have proven to be unsatisfactory because fog and clear air turbulence seriously interfere with those lasers performance The use of ultrashort pulse lasers he believes will circumvent these problems It s really about how we re using the energy said Chaffee In December 2013 Vargas and Chaffee s collaboration got under way in earnest after they received a grant for just under 100 000 from the Commonwealth Research Commercialization Fund with an equivalent match from Attochron The CRCF program which is administered by the Center for Innovative Technology is a state fund designed to advance in Virginia targeted areas of research with commercial promise With funding secured Vargas and Chaffee have been hard at work this year in a lab in the basement of Mallory Hall with assistance from Attochron s chief technology officer of USPL Systems Dr Alexandre Braga of Albuquerque N M Together the three are working to prove that ultrashort pulse lasers could someday complement microwave radios and fiber optics as a means of communication between cell phone towers Such tower to tower or tower to network communication is known in industry parlance as backhaul According to Chaffee backhaul is in short supply as more and more individuals use their phones to send and receive vast amounts of data such as pictures and video There s a capacity crunch in backhaul networks said Chaffee That s the worldwide number one problem for wireless telecommunications Fiber optics laser signals inside glass fiber can carry vast amounts of data Chaffee noted but their installation requires digging That digging in turn requires obtaining permits and dodging infrastructure that may already be underground By instead sending the lasers through the air these problems can be avoided entirely It s kind of like getting the fiber optic capacity without the fiber observed Chaffee A typical speed for microwaves Vargas said is 100 to 300 megabits per second while the speed of USP lasers is measured in gigabits per second There are 1 024 megabits in one gigabit The big advantage of going from microwaves to lasers in wireless communications is going from megabits to gigabits Vargas commented By the end of this year Vargas Chaffee and Braga hope to send a modulated ultrashort pulse laser signal with a data rate of at least one gigabit per second between an upstairs classroom in Mallory Hall and the press box in Foster Stadium On our previous working session in August we sent just the laser pulses but on Sept 19 we sent a 100 Mbps modulated signal a new record for Attochron said Vargas She explained that a modulated laser signal carries data and signals used in telecommunications must be able to carry data Just sending the laser is simple but sending a modulated signal is much more complicated Vargas noted To prove that ultrashort pulse lasers can work in all weather conditions Vargas

  • Tracking Movement to the Microsecond
    got some ideas that we re going to work on over the summer The lab consists of equipment provided through several sources including a Jackson Hope grant for acquisition of a Nd YAG laser a powerful laser based on yttrium aluminum and garnet crystals The Jackson Hope grant of 77 000 allowed us to get this key piece of equipment said Taylor VMI as a whole chipped in another 46 000 and the department added another 60 000 These funds paid for the customization of a space in NEB for the laser lab acquisition of a high sensitivity ICCD camera and construction of a housing for the entire system You can think of the lab as a really expensive camera system with an even more expensive flash said Taylor The idea is that you shoot a laser to illuminate a small quantity of gas When the laser hits the gas it glows so you can image the glow and track how it moves The system tracks that movement with extreme precision allowing researchers to capture data on the order of microseconds or nanoseconds millionths or billionths of a second We re still fine tuning the system It s not an easy experiment by any means said Brooke There are a lot of aspects to coordinate you ve got the laser and the camera and everything has to link together and trigger within nanoseconds so it has been a learning process but we ve made a lot of progress Cadets are already taking advantage of the facility Kelsey McCusker 13 is using the lab to study heat flow inside miniature structures as part of her honors thesis The lab allowed McCusker to study the airflow for a given space by using the laser to illuminate gases while the camera captured data
