Fortunately , I made use of the Indigo Laser and was able to do the surgery very safely with the newest technology . The current prototype uses visible light and two cameras to find CCDs , but a future commercial system might use invisible infrared lasers and photo-detecting transistors to scan for contraband cameras . Hiring contractors would mean a steep learning curve for people not knowledgeable about lasers and the goals of the complex project . I also learned a lot about lasers and optic fibers , not to mention machinery , and a good idea of what behind the scene Disney is like . Here is a guy who has spent the past 42 years thinking about lasers and little else . The most significant advantage offered by this approach , which utilized near infrared lasers and interferometric detection , was the dramatic minimization of fluorescence interference in Raman scattering . Specific examples of the scientific / economic advances that have originated from university laboratories include laser and fiber optic research at the heart of the telecommunications boom , supercomputer research that led to the Internet and recombinant DNA research that created the biotech industry . The Company 's products include laser and inkjet printers , scanners , copiers and faxes , personal computers , workstations , storage solutions , and other computing and printing systems . Network services available within the department include laser and color printing facilities , CD-ROM / DVD access and recording , scanners , video , and various media storage facilities . Today 's triplexers are made in two separate steps : optical waveguides are deposited on a chip , and then separately housed lasers and detectors must be carefully aligned and attached to the waveguides .
