This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.

We propose a new method for creating an optimal coherence in a two-level system (TLS) based on adiabatic following. Optimal coherence is achieved by choosing the time-dependent phase of the pulse that provides vanishing field-TLS detuning dðtÞ at central time when the pulse amplitude reaches maximum. For example, dðtÞ 1⁄4 d0ð1 expððt t0Þ=s0ÞÞ for t 6 t0 and d 1⁄4 0 for t > t0. The pulse envelop...

There are various types of lasers available for hair reduction, but the choice of an ideal laser for ethnic skin has its own limitations. The choice of the right laser for the right skin type is very important. Before starting with the laser therapy, it is important to assess the skin type, the fluence, the pulse duration and the type of laser to be used.

OBJECTIVES To explore the effects of various factors related to the industry, the contaminant, and the period and type of sampling on long term declining trends in occupational exposure. METHODS Linear regression analyses were used to assess the relation between reductions in exposure and geographical location, industrial sector, type of contaminant, type of monitoring, carcinogenic classific...

We designed a behavioural paradigm for vibro-tactile detection to characterise the sampling time and performance in the rat whisker sensory system. Rats initiated a trial by nose-poking into an aperture where their whiskers came into contact with two meshes. A continuous nose-poke for a random duration triggered stimulus presentation. Stimuli were a sequence of discrete Gaussian deflections of ...
