We hope that our results will stimulate other researchers to improve them by further reducing the lasing threshold, or increasing the range of emitted colours,' said lead researcher Professor Jaime Gomez Rivas.
The outlet temperature of the mercury was varied from 50 to 250[degrees]C (the partial pressure of the mercury vapour ranged from 1 Pa to 10 kPa), but the lasing threshold was not reached [8, 17].
Let us evaluate the lasing threshold, without taking into account the nonresonance losses.
defines structure eigenmodes at lasing threshold, i.e., in the linear case.
has announced its Neodymium Doped Gadolinium Vanadate (Nd:GdV[O.sub.4]) laser crystals that are suitable for diode pumped solid state (DPSS) micro/mini lasers because of their high power output, high slope efficiency, good thermal conductivity, low lasing threshold and high laser-induced damage threshold.
The lower end of the range is defined as the lasing threshold. Above that is a linear operating region.
