  • SINGLE-LINE-EXTRACTED PURE ROTATIONAL RAMAN LIDAR TO MEASURE ATMOSPHERIC TEMPERATURE AND AEROSOL PROFILES
    Publication number: 20180188376
    Abstract: A single-line-extracted pure rotational Raman lidar system, including: a transmitter unit configured to emit extremely narrow-band laser light that is guided into atmosphere zenithward; a receiver unit configured to collect backscattered signals from the atmosphere; and a data acquisition and control unit configured to deliver data and guarantee automatic operation of the lidar system orderly. The transmitter unit employs a powerful injection-seeded Nd: YAG laser to emit 532.23 nm laser beam with a pulse energy of approximately 800 mJ, a repetition rate of 30 Hz and linewidth of <0.006 cm?1. The lidar system has an optical bandwidth of approximately 30 pm for the two Raman channels and an optical bandwidth of 0.3 nm for an elastic channel, as well as a field of view of approximately 0.4 mrad. The two Raman channels extract the N2 anti-Stokes pure rotational Raman line signals with J=6 and 16, respectively.

  • Techniques for decreasing multiprotocol label switching entropy label overhead
    Patent number: 9912598
    Abstract: A method is provided in one embodiment and includes receiving at a network element an encapsulated packet and determining whether both an ECMP/LAG Existing (“ele”) flag and an Entropy Label Capability (“elc”) flag are set for an egress node of the packet in a Label Distribution Protocol (“LDP”) database of the network element. If both the ele and elc flags are set for the egress node of the packet in the LDP database, the method further includes determining whether the network element is an ingress node for the packet and, if the network element is the ingress node for the packet, pushing an Entropy Label (“EL”) and an Entropy Label Indicator (“ELI”) onto an MPLS stack of the packet.
