The possibility of stable excitation of a high axial mode in the traveling-wave tube regime in gyrotrons is demonstrated. This regime provides a significant efficiency enhancement in high-harmonic low-current gyrotrons.

Coherent subterahertz radiation is achieved for the first time in the large-orbit gyrotron operating at a higher cyclotron harmonic in the continuous-wave generation regime. A stable generation is achieved in the case of operation at the third and th

Thermal scanning probe lithography (t-SPL) is a direct-write patterning method that creates high-resolution features with a heated scanning probe tip in an organic resist material. It is able to produce dense high-resolution patterns with sub-20 nm h

We describe high-harmonic gyrotrons with axis-encircling electron beams developing on the basis of two (80 keV pulsed and 30 keV Cw) experimental setups. Selective operation at the second (0.267 THz) and at the third (0.394 THz) cyclotron harmonics w

An important problem in realization of gyrotrons operating at high cyclotron harmonics is discrimination of parasitic oscillations exited at lower harmonics. In this work, we describe various schemes of gyrotron cavities with short irregularities pro

Recent investigations have shown that electrohydrodynamic (EHD) flows caused by the field-enhanced dissociation can emerge near solid insulation elements, which makes it possible to create a fundamentally new scheme of an EHD pump, where the key elem

Free carrier absorption in heterostructure layers of an operating laser diode has been measured. The proposed technique is based on coupling pulse probe light emission into the laser waveguide. Lasers with various heterostructure designs were measure
