“…In order to overcome this limitation, we decided to use, for SR diagnostics, streak image tubes of PIF-01/S1 type, which were developed and have been continuously manufactured at the Photoelectronics Department of A. M. Prokhorov General Physics Institute since the eighties [7]. The experimentally proved limited temporal resolution of such tubes approaches 1±0.2 ps in a single streak mode at 2•10 10 cm/s streak speed and 3 kV/mm electric field strength near the photocathode surface, when femtosecond laser pulses illuminate the tube-input photocathode at 800 and 911 nm wavelength [8,9].…”

Experimental study of beam profile dynamics at circular accelerator was carried out due to creation of the sources of synchrotron radiation and colliders, at which the beam consists of several tens or hundreds of bunches distributed over the separatrices. Dynamics of a longitudinal profile of separate bunches was studied by means of streak cameras, however, they are not applied for regular, permanent diagnostics unlike beam position monitors or CCD cameras Streak cameras are very good for study of single processes, not for routine accelerator performance. BINP SB RAS has developed the optical analyzer on the basis of LI-602 dissector which was used for studying the beam dynamics at VEPP-2, VEPP-3, VEPP-4, electron-positron colliders and other electron circular accelerators: Siberia-2, ESRF, etc The dissector provides permanent measurements of the longitudinal beam profile. Nevertheless, the ultimate temporal resolution of the device is about 20 picoseconds Now it is not enough for application at modern accelerators. In this paper we describe the first experimental results obtained with the dissector of the next generation. The measured technical resolution of this device is about 2 picoseconds, but we believe that this value can be improved.

“…4 (c) ), six individual longitudinal modes were clearly resolved and were separated by a mode spacing of ~11 GHz. The laser output pulse energy (~1 pJ) was insufficient to permit measurement of the pulse duration by autocorrelation method so we employed a high-speed optoelectronic streak camera PS-1/S1 29 with a 1-ps temporal resolution. The measured streak-camera trace and corresponding sech 2 (t) fit are shown in Fig.…”

We report stable, passive, continuous-wave (CW) mode-locking of a compact diode-pumped waveguide Nd:YAG laser with a single-layer graphene saturable absorber. The depressed cladding waveguide in the Nd:YAG crystal is fabricated with an ultrafast laser inscription method. The saturable absorber is formed by direct deposition of CVD single-layer graphene on the output coupler. The few millimeter-long cavity provides generation of 16-ps pulses with repetition rates in the GHz range (up to 11.3 GHz) and 12 mW average power. Stable CW mode-locking operation is achieved by controlling the group delay dispersion in the laser cavity with a Gires–Tournois interferometer.

“…After the amplification the pulse energy approached 30 mJ with a repetition rate 2 Hz, and the radiation polarisation was vertical. The pulse duration was measured using a PS-1/S1 streak camera [29,30], developed and fabricated at the General Physics Institute, Russian Academy of Sciences. In the streak camera the electro-optical converter (EOC) with a silver - oxygencaesium photocathode was used.…”

The scheme generating UV pulses with a duration 15 ps and output energy up to 11.5 mJ is implemented in the system consisting of a picosecond Nd 3+ : YAG laser with multistage nonlinearoptical conversion of fundamental frequency radiation into radiation with a wavelength 193 nm followed by an excimer ArF amplifier. The temporal characteristics and the contrast of the amplified pulses are measured.
