Modes structure

Figure Bl.4.9. Top rotation-tunnelling hyperfine structure in one of the flipping inodes of (020)3 near 3 THz. The small splittings seen in the Q-branch transitions are induced by the bound-free hydrogen atom tiiimelling by the water monomers. Bottom the low-frequency torsional mode structure of the water duner spectrum, includmg a detailed comparison of theoretical calculations of the dynamics with those observed experimentally [ ]. The symbols next to the arrows depict the parallel (A k= 0) versus perpendicular (A = 1) nature of the selection rules in the pseudorotation manifold.

Dinitrogen might coordinate to metals in at least 4 ways, but only the end-on modes, structures (1) and (2), are well established as common bonding modes by numerous well-defined examples ... 

Iral modes within the narrow peak. However, mode structure was not observed in any of our measurements. Since both ASE and lasing are based on stimulated emission, the difference is not very important in the context of the electrically pumped organic laser. Moreover, because the distinction is not a key issue here, we consider the gain phenomena observed in systems without external feedback to be mirmrless lasing. 

The WGM laser mode structure is determined by the droplet size and shape (which can be influenced by optical trapping forces26), laser polarization, and dye concentration. ... 

The alignment of these predicted OB-fold domains is consistent with a conserved arrangement of the secondary structure elements that are seen in the ModE structure and suggests that all members of this family form an interlocked structure (Fig. 2B,C). Furthermore, secondary structure...

The CO2 lasers were also investigated in connection with chaotic behavior, and here we mention the most important papers in the field. The chaotic behavior associated with a transverse mode structure in a cw CO2 laser was observed in 1985 [40]. In the CO2 laser with elastooptically modulated cavity length, a period doubling route to chaos was also found [41].

IRS and OHD-RIKES are less effected by the background interference, but the signal levels tend to be low, and they are subject to noise in the broad-band dye laser probe. Attempts to eliminate the remaining noise by time dispersal of the Raman signal and local oscillator by means of a streak camera (9) or a smoothing of the dye probe mode structure by intracavity phase shifting of the dye radiation are under consideration. 

Moreover, in recent years broad band lasers have appeared which lack any frequency modal structure, at the same time retaining such common properties of lasers as directivity and spatial coherence of the light beam at sufficiently high spectral power density. The advantages of such a laser consist of fairly well defined statistical properties and a low noise level. In particular, the authors of [245] report on a tunable modeless direct current laser with a generation contour width of 12 GHz, and with a spectral power density of 50 /xW/MHz. The constructive interference which produces mode structure in a Fabry-Perot-type resonator is eliminated by phase shift, introduced by an acoustic modulator inserted into the resonator. 

S-NDR systems (4DL inhibitor Turing-like structures (n > 1) standing waves, anti-phase oscillations with n = 1 or mixed-mode structures with n > 1 pulses stationary domains (n = 1 or n > 1)... 

The spectral width of a pulse train emitted by a femtosecond laser can be significantly broadened in a single mode fiber [27]. This process that maintains the mode structure is described in the time domain by the optical Kerr effect or selfphase modulation. The first discussion is simplified by assuming an unchanging pulse-shape under propagation. After propagating the length l the intensity dependent refractive index n(t) = n0 + ri2/(f) leads to a self induced phase shift...
