An increased range guided projectile includes overcaliber lateral moment reducing wings (10) that can be deployed. The lateral moment reducing wings (10) are designed and arranged behind the center of gravity (S) in the tail direction on the guided projectile (1) so that the pitching moment derivative coefficient (C_(m)) of the guided projectile (1) is in the range of 0.5, if the guided projectile (1) has a speed that is in the speed range of Mach 0.4 to 0.8; the lateral moment reducing wings (10) are in their deployed position; and, the canard guide device (20) does not exert any guiding moments.

The CONPHIRMER consortium has come together to put into the hands of customs officers and other agents of law enforcement a portable and easy-to-use sensor for telling genuine medicines from fakes without having to remove the medicines from their packaging. With this device agencies charged with tackling the growing menace of the trafficking in counterfeit medicines will be able to screen packaged pharmaceuticals at EU borders and airports quickly and accurately using a non-invasive and non-destructive technology that uses only harmless radio waves. The proposal is for a three-year programme leading to the trialing of a prototype, portable, handheld scanner, that will draw on the expertise of seven organisations in five states, including two recent additions to the EU family, Poland and Slovenia. The technology employed will be based on quadrupole resonance (QR), a radiofrequency (RF) spectroscopic technique that has already been developed and deployed for the detection of concealed explosives. The completed prototype will not require operators to have special chemical or technical knowledge to deploy it, allowing training in its use to be completed quickly; and it will utilise only easy to source RF and electrical parts, unlike alternative technologies such as Raman, infra-red or terahertz spectroscopic methods. It will also offer a clear advantage over these other technologies in that RF can penetrate even multiple layers of packaging material, allowing for scans to be carried out without the need to remove pharmaceutical products from their packaging.

Singly 0.5 at.% Ho doped crystals of YLiF4 (YLF) and LuLiF 4 (LLF) are studied under identical pump conditions in continuous-wave (CW) and Q-switched operation. Longitudinal end-pumped CW laser performance shows Ho:LLF to have a slightly lower threshold and a slightly higher slope efficiency with respect to absorbed pump power than Ho:YLF. Both lasers were operated on π-polarization. At a cavity output coupling of 20% and a crystal length of 30 mm, the Ho:LLF (Ho:YLF) laser yielded 18.8 W (18 W) of CW output at a wavelength of 2067.8 nm (2064.0 nm) for 41.4 W (42.2 W) of absorbed pump power with a slope efficiency of 67.1% (65.6%) and an optical-to-optical efficiency of 45.4% (42.6%) with respect to absorbed pump power. With the same output coupling and a crystal length of 40 mm, the Ho:LLF (Ho:YLF) laser yielded 20.5 W (18.1 W) of CW output at a wavelength of 2067.7 nm (2064.3 nm) for 51.5 W (50.0 W) of absorbed pump power with a slope efficiency of 58.4% (55.4%) and an optical-to-optical efficiency of 39.8 (36.1%) with respect to absorbed pump power. The influence of the temperature of the cooling mount on CW laser performance was studied and showed very similar results for both laser materials. At full pump power, a slope of-155 mW/°C (-149 mW/°C) was observed for the Ho:LLF (Ho:YLF) laser with a crystal length of 30 mm. In Q-switched operation, the Ho:LLF (Ho:YLF) laser produced 37 mJ (38.5 mJ) at a repetition rate of 100 Hz with a pulse duration of 38 ns (35 ns) at a wavelength of 2053.1 nm (2050.2 nm) with a slope efficiency of 30.3% (31%) and an optical-to-optical efficiency of 14.2% (13.9%) with respect to absorbed pump power. The beam quality was nearly diffraction limited (M2 < 1.1). © Springer-Verlag 2011.

A Q-switched Trn:fiber-laser-pumped Ho : LuLiF4 laser is reported that has been optimized for high-energy pulses at low repetition rates. Operating at 100 Hz, a pulse energy of 24.8 mJ with pulse widths of 47 ns at a wavelength of 2052 nm was achieved. The beam propagation factor (M2) was measured to be ∼1.04 at the maximum pump power, confirming fundamental transverse mode (TEM00) operation. Starting the pump laser at maximum power, the pulse energies of each of the first 10 pulses are >47 mJ. This strong influence of crystal temperature on laser performance is discussed with the prospect for further improvement of the laser efficiency. © 2010 Optical Society of America.
