This Letter reports an average lasing efficiency of 6525 from a multi-waveguide 25 mol.

. In this way the threshold pump power for this particular laser can be found. The laser samples used in this study were prepared by dispersing a low concentration by weight of a high twisting power. Ytterbium-doped ZrF4-BaF2-LaF3-AlF3-NaFYbZBLAN chip in an extended-cavity configuration.

The slope efficiency is an important property of a laserwikipedia. Slope Efficiency in laser is the efficiency by which the input pump power is converted into signal power. This excerpt gives a succinct explanation of Threshold and Slope Efficiency in a laser.

Slope efficiency is the efficiency a change in power output with a change of power input. Depending on various quantities a certain value of the output coupler transmission will optimize the overall power efficiency of a laser. This is the basis of my patents on high photovoltaic efficiencies and the basis of my IP for solar pumped lasers.

Although not as apparent as threshold shift laser efﬁ ciency also falls off with increasing temperature Figure 2. Questions and Comments from Users. Above the lasing threshold the resulting curve is usually close to a straight lineThe slope efficiency is the slope of this line.

More signiﬁcantly that the slope efﬁciency is increased from 39 to 60. Online access to SPIE eBooks is limited to subscribing institutions. The slope efficiency reaches 73 with respect to absorbed power 60 considering coupled power for a maximum signal power of 62 W delivered on a quasi single spatial mode M 2 12.

In simple situations the slope efficiency is essentially determined by the product of the pump absorption efficiency the ratio of laser and pump photon energy quantum defect the quantum efficiency of the gain medium and the output coupling efficiency of the laser resonator. We show that the slope efficiency of the hybrid laser can be efficiently increased by controlling the external cavity phase improving the coupling between the laser chip and passive chip using optimized anti-reflection and high reflection coatings and. Whatever the shape of a slope efficiency curve it should be possible to extrapolate the line of best fit to find the intercept with the x-axis.

Normally power increases linearly until the laser begins to saturate and then reaches a peak as shown at the right. The slope efficiency is an important property of a laserIt is obtained by plotting the laser output power against the input pump power. This is usually highest when the wavelength of the pumping light source matches the band gap of the Fabrey Perot cell that forms the laser.

Slope efficiency can similarly be defined in terms of output and input energies instead of powers. Output of a laser as a function of input power where the efficiency at any point on the curve is the input power divided by the output power and the slope efficiency measures how fast the output increases relative to the input. For a medium to be able to amplify incident radiation the state of population inversion must prevail in the medium.

It is one of the most important properties of a laser and is simply the slope of the output power versus input power. To the best of our knowledge this slope efficiency is the highest reported for a high power clad-pumped fiber laser emitting at a wavelength higher than 21 m.

It is most commonly expressed as slope efﬁ ciency and measured in units of mWmA. Determining the laser threshold periodically via a slope efficiency graph is particularly useful in helping to determine. The efﬁ ciency of a diode laser is also derived from the LI curve.

Laser efﬁ ciencies are typically about 03 mWmA at. In simple cases the slope efficiency can be calculated as the product of several efficiency factors one of them being the output coupling efficiency. It can be elucidating to compare the slope efficiency with the differential quantum.

When increasing the fiber length from 005 to 5 m the slope efficiency and maximum laser output power both improve enormously by about 20 times from 132 and 0259 W to 2747 and 5209 W. A threshold current and a. In a method of controlling an injection-seeded laser a response of the laser is sampled at a plurality of different laser current values.
