Backward supercontinuum emission from a filament generated by ultrashort laser pulses in air.

Backward emission of the supercontinuum from a light filament induced by high-intensity femtosecond laser pulses propagating in air has been observed to be enhanced compared with linear Rayleigh-Mie scattering. This enhancement is interpreted as a nonlinear scattering process onto longitudinal refractive-index changes induced by the laser pulse itself. The spectral dependence of the supercontinuum angular distribution is also investigated.

Infrared extension of the super continuum generated by femtosecond terawatt laser pulses propagating in the atmosphere.

We investigated the spectral behavior of a white-light continuum generated in air by 2-TW femtosecond laser pulses at 800 nm. The spectrum extends at least from 300 nm to 4.5 mum. From 1 to 1.6 mum the continuum's intensity increases strongly with the laser energy and depends on the initial chirp.

High-order harmonics from solid targets as a probe for high-density plasmas.

The interaction of 100-fs Ti:sapphire laser pulses with thin foil targets was experimentally investigated at intensities exceeding 10(18) W/cm(2). High harmonics were observed in transmission through an overdense plasma in the direction of the incident beam. From the cutoff frequency of the harmonics an electron density of 1 x 10(24) cm(-3) is inferred, indicating a compression of the plasma by the ponderomotive force of the laser pulse.

[Animal experiment studies on the problem of treating corneal lesions]. / Tierexperimentelle Untersuchungen zur Frage der Behandlung von Hornhautläsionen.

From the clinical point of view an ointment containing retinol, thiamine hydrochloride and calcium pantothenate (Regepithel) seems to be of benefit in the treatment of various corneal diseases. The influence of Regepithel on healing time after superficial corneal injuries in rabbits is demonstrated on the basis of comparative histological findings.

[Treatment of glaucoma with a pilocarpine-dipivefrin combination (author's transl)]. / Glaukomtherapie mit Pilocarpin/Dipivefrin-Kombination.

The author considers that the combined use of pilocarpine and Dipivefrin (Thiloadren) represents an additional effective method of regulating pressure as physiologically as possible in glaucomatous eyes with trophic disorders, thus further reducing the need for surgery. The efficacy of this drop combination is demonstrated with reference to 71 glaucoma patients. The advantages of 0.1% Dipivefrin as compared to 1% epinephrine are pointed out.

[The polyviol implant (author's transl)]. / Zur Frage der Polyviolplombenanwendung bei der Netzhautoperation.

It can be confirmed still today the polyviol implant occupies an outstanding position as a kind of material for implants used within retinaoperations refering to Custodis. The polyviol implant sets an example that in ophthalmology it is the best way to test synthetic material on monkey's eye before really introducing them. As far as the sclera is concerned, the histologic cut of the conjunctival covering allows a conclusion on physiologic compatibility of the implant material.
