The pulse-buildup in miniature passively Q-switched lasers occurs in a similar time-scale as the phonon-assisted thermalization of the laser manifolds. We study how the time-dynamics of the laser is affected by the thermalization and relaxation proce

We exploit nondegenerate four-wave mixing to generate narrow-bandwidth visible light from blue to orange in microstructured optical fiber. The process is excited by nanosecond dual-wavelength pump pulses (532/1064 nm) produced by a frequency-doubled

We report on generation of 946 nm laser pulses of a few nanosecond duration and up to 3.7 kW peak power from a compact diode-pumped passively Q-switched Nd:YAG laser. This power is 2.5 times as much as what previously has been obtained from this type

A microcavity laser pumped by a pulsed evanescent optical wave is demonstrated. The laser radiates intense, linearly polarized light isotropically in a plane perpendicular to the axis of the cylindrical microcavity. The lasing was achieved by surroun

We demonstrate a simple and compact laser source that directly produces a Bessel–Gauss beam. The laser resonator consists of a diode-end-pumped Nd:YAG crystal, a planar mirror, and a diffractive mirror designed to phase-conjugate only the lowest-or

We examine the idea to use self-focusing in a non-linear liquid crystal to increase the accuracy of measurements of wavefront distortions with an active Shack–Hartmann sensor. This modification should improve the measurement accuracy by two orders

We present a simple method to convert a Gaussian laser beam into an annular beam using a homeotropically oriented nematic liquid crystal. The method allows creation of a beam with sub-millimeter diameter and a width of a few tens of microns for a pro

The application of a new microchip laser source for Raman spectral measurements is demonstrated. The performance of the device is evaluated and illustrated by Raman spectra of diamond thin films and a solid-state laser host material.
