Lancaster, D.Rehle, D.Leleux, D.Tittel, F.2010-08-192010-08-192000Proceedings of the Conference on Lasers and Electro-Optics (CLEO) San Francisco, CA, USA, 2000: p.5141557526346http://hdl.handle.net/2440/59906Summary form only given. To increase the difference-frequency power produced in an optical trace gas sensor we have developed an architecture based on two frequency-stable diode lasers at 1.1 and 1.5 μm, which are amplified by high-power Yb and Er-doped fiber amplifiers, respectively. To date we have generated up to 0.7 mW of narrow-band (<60 MHz) mid-infrared radiation.enCopyright status unknownConference paper003000113710.1109/CLEO.2000.90732865143
