…several wavelengths in the range 229 nm to 257 nm. The very short wavelengths of these CW lasers minimize sample damage, compared with nanosecond pulses lasers, and minimize excitation of competing fluorescent signal. A dynamic field of Raman studies is coherent anti-Stokes Raman scattering, or…

…specification, using an EnergyMax sensor with a laser that has a pulse
width longer than the specified maximum pulse width will
result in increased measurement error. For example, if you use
the sensor with double the maximum pulse width, the result
will be an additional 2 to 3%…

…these pulses are coherent in phase and
completely controllable in time and, ideally, in polarization also. The entire sequence of pulses
is illustrated schematically in figure 2.

…generating extremely short
pulses (like Vitara UBB) are subject to strong pulse
broadening because of the dispersive effects taking
place during propagation in any material.
A simple 1 millimeter thick fused silica plate will
double the output pulse duration of the laser…

…very flexible operation, from single pulses up to 50 MHz. Moreover, the total output power is virtually unaffected by changes in the pulse rate up to several MHz; doubling the pulse rate only cuts the pulse energy by 50 percent (Figure 1). The pulsing flexibility also supports so-called seeder…

Generating CEP-Stabilized Coherent THz Pulses
In 2008, the Huber group demonstrated a method of
generating THz pulses where the phase between the
electric field oscillations and the carrier envelope of the
pulse is very stable and readily adjustable. The work

systems are 0.5 times the given values for the TeO2 cell.
4 For SHG operation, the fundamental output must be pulse picked first, then frequency doubled.

Currently, the optimum laser technology for
this process is the frequency doubled
(532 nm), solid-state, nanosecond pulse
width laser, typically operating in about the
40 W output power range. This gives the best

In response to extended light pulses, the photocurrents of most
known ChRs decline from an initial peak current to a lower,
stationary level, a phenomenon known as desensitization…
