Holmild’s laser source description does not indicated a chirped laser source IMHO.
Axil—What do yo mean by “carrier material”? As Axil has pointed out, the experimental process would not seem to produce much plasma, if any, and I doubt a plasma would support the surface reaction Holmild suggests.. Does anyone know what the reaction of a anti-proton/proton annihilation produces—are there typically muons observed or only energetic photons, back to back? ( The following description from Wikipedia does not seem to apply since the input energy is to low— “ When a proton encounters its antiparticle (and more generally, if any species of baryon encounters the corresponding antibaryon), the reaction is not as simple as electron-positron annihilation. Unlike an electron, a proton is a composite particle consisting of three "valence quarks" and an indeterminate number of "sea quarks" bound by gluons. Thus, when a proton encounters an antiproton, one of its quarks, usually a constituent valence quark, may annihilate with an antiquark (which more rarely could be a sea quark) to produce a gluon, after which the gluon together with the remaining quarks, antiquarks and gluons will undergo a complex process of rearrangement (called hadronization or fragmentation) into a number of mesons, (mostly pions and kaons), which will share the total energy and momentum. The newly created mesons are unstable, and unless they encounter and interact with some other material, they will decay in a series of reactions that ultimately produce only gamma rays, electrons, positrons, and neutrinos. This type of reaction will occur between any baryon (particle consisting of three quarks) and any antibaryon consisting of three antiquarks, one of which corresponds to a quark in the baryon. (This reaction is unlikely if at least one among the baryon and anti-baryon is exotic enough that they share no constituent quark flavors.) Antiprotons can and do annihilate with neutrons, and likewise antineutrons can annihilate with protons, as discussed below. Reactions in which proton-antiproton annihilation produces as many as nine mesons have been observed, while production of thirteen mesons is theoretically possible. The generated mesons leave the site of the annihilation at moderate fractions of the speed of light, and decay with whatever lifetime is appropriate for their type of meson.[4] Similar reactions will occur when an antinucleon annihilates within a more complex atomic nucleus, save that the resulting mesons, being strongly interacting, have a significant probability of being absorbed by one of the remaining "spectator" nucleons rather than escaping. Since the absorbed energy can be as much as ~2 GeV, it can in principle exceed the binding energy of even the heaviest nuclei. Thus, when an antiproton annihilates inside a heavy nucleus such as uranium or plutonium, partial or complete disruption of the nucleus can occur, releasing large numbers of fast neutrons.[5] Such reactions open the possibility for triggering a significant number of secondary fission reactions in a subcritical mass, and may potentially be useful for spacecraft ‘propulsion.’ It may be that the laser pulse changes the charge on one or two protons or deuterons similar to the mechanism for creation of electron/positron pairs or merely disrupts the coupling of existing Cooper pairs of p or D(0) itself. (I do not buy the quark-gluon theory expressed above in the Wikipedia quote.)

That is important. Since it is simply a plain vanilla low-powered-pulse from a ow priced laser ... but it a pulse which works... and if we believe it works, then that tells us much about the physics involved. Yet it is not new physics. The yellow-green light frequency is important. In fact, this result is reported in the literature going back a decade; but it is overlooked that laser fusion at low power has been demonstrated a number of times using this exact frequency of light from several other labs - and to little fanfare, such as here: http://lenr-canr.org/acrobat/TianJexcessheatb.pdf There are other papers where 532 nm lasers have produced anomalous fusion. Maybe other frequencies work, maybe not. If we could be certain that Holmlid is correct, then what he has done is to show that the process for fusion involves muon production, which is far more energetic than nuclear fusion - and the total annihilation of hydrogen nuclei can be done without chirping. That is huge ... even if it has been overlooked for a decade. Even if it is a QM effect which does not scale, it is huge since there is a faction of the output which is charged particles and that means the effect can be more than additive.

The laser beam is focused at the test surface with an f = 400 mm spherical lens. The intensity in the beam waist of (nominally) 30 lm diameter is relatively low, 4 <10e12Wcm 2 as calculated for a Gaussian beam Brian Ahern wrote: Holmlid has left out the most important experimental detail. What is the laser like? I suspect it is chirped into the exowatt range where anything can happen. This is a rich field that does not require any suppositions about dense hydrogen. Large accelerators became nearly obsolete by the chirped laser capabilities since 1998.
