The Bombardier Invitation is a Canadian sailing dinghy that was designed by Bombardier Research to compete in the same market with the Laser, as a one-design racer. It was first built in 1973. [1] [2] The design was developed into the Bombardier 3.8 in 1974. [3]
If the baseline value is small or subtracted out, the knife-edge beam width always corresponds to 60%, in the case of 20/80, or 80%, in the case of 10/90, of the total beam power no matter what the beam profile. On the other hand, the D4σ, 1/e 2, and FWHM widths encompass fractions of power that are beam-shape dependent. Therefore, the 10/90 ...
These are the highest peak-power pulsed laser diode arrays in the world. [17] L4 ATON – 10PW laser, 2 kilojoule – status: in operation - This laser system is designed to generate an extremely high peak power of 10 PW (Petawatt) in pulses with duration of 150 fs, pulse energy 1.5 kJ and repetition rate 1 shot per minute. [18]
The Gaussian function has a 1/e 2 diameter (2w as used in the text) about 1.7 times the FWHM.. At a position z along the beam (measured from the focus), the spot size parameter w is given by a hyperbolic relation: [1] = + (), where [1] = is called the Rayleigh range as further discussed below, and is the refractive index of the medium.
Fig. 2: Repeated total internal reflection of a 405 nm laser beam between the front and back surfaces of a glass pane. The color of the laser light itself is deep violet; but its wavelength is short enough to cause fluorescence in the glass, which re-radiates greenish light in all directions, rendering the zigzag beam visible.
M 2 is useful because it reflects how well a collimated laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. It is a better guide to beam quality than Gaussian appearance because there are many cases in which a beam can look Gaussian, yet have an M 2 value far from unity. [1]
The FZ275 LGR - Laser Guided Rocket is a weapon system by Thales (formerly Forges de Zeebrugge). It is intended to provide a low-cost guided missile compatible with existing unguided 70mm rocket launch platforms. The HE (High Explosive) version of the FZ275 LGR is equipped with a HE warhead with impact fuze. [5]
