Laser power outputs

Figure 5 shows three data points for the linewidths measured for a single mode PhSi-xSe diode laser (indicated by circles) in addition to the linewidth of the laser illustrated in Figure it (indicated by a square). Figure 5 shows the linewidths plotted as a function of the inverse of the single-ended laser power output. A linear extrapolation of the three data points of the single mode laser to zero inverse power indicated negligible linewidth intercept. Hence, the power-independent...

Figure 3.5 gives a schematic illustration of the key elements of a cw CO chemical laser. Mixing of CS2 with O atoms occurs in a subsonic mixing zone a transverse optical axis is employed. Typical cavity pressures in cw CO lasers range from about 5 to 50 torr. Chemical efficiencies for these lasers can exceed 30% based on the fraction of the energy release of reaction (3.2) which appears as laser power output. ...

If faster scanning rates are required for some specific applications they can easily be reached either by increasing the power output of the laser up to 5 W, or by focusing the beam down into the micron range. Table I compares the results obtained with the unfocused laser beam and with a 100 or 10 pm laser spot. With the most sharply focused beam, carbonization alrealy occured at a scanning speed of 50 cm s-1 and the exposure time dropped into the microsecond range. 

Thorn EMI 9235QB) near the phosphor screen to collect all of the ion signal as the probe laser was tuned over the 0(3Pj) Doppler profile at laser wavelengths of 226.23, 226.06 and 225.65 nm for j = 0, 1 and 2, respectively. The output of the photomultiplier was sent to a boxcar averager gated at the appropriate arrival time. The probe laser power was simultaneously measured with a photodiode in order to normalize the 0(3Pj) signal intensity for fluctuations in laser power.
