Periodic ripples are observed to develop at the surface of faceted chemical vapor deposited diamond films during laser irradiation at an angle of incidence beyond a critical value. The grating pattern perpetuates itself across the surface upon irradi

The possibilities of construction and application of laser diode-pumped solid-state lasers are described. The wavelength of the most powerful available diodes is well suited for the excitation of trivalent rare earth ions such as Nd3+, Tm3+ and Er3+

The characteristic properties of flashlamp- and laser excited erbium doped crystal or glass lasers are reviewed. The excitation mechanisms are discussed in detail. In particular it is shown that with moderate pumping inversion in a heavily doped flas

The temperature dependence of the laser threshold and the slope efficiency of a YAG:Er laser operated at 2.94 μm have been measured. With a reduction of the temperature from 55 to 4 °C the output of the YAG:Er laser can be increased by a factor of

Erbium-doped fluorozirconate (ZBLAN) fibers are promising candidates for the construction of compact and efficient all-solid-state 3-µm laser sources for surgical applications. Excited-state absorption (ESA) was found to have a major influence on th

Application of polycrystalline diamond films in laser optics and electronics calls for detailed knowledge on mechanisms of their photoexcitation. As was recently reported, an exposure of the chemical vapour deposited (CVD) diamond films to UV radiati

Micro-surgical applications using 3 µm Erbium lasers demand a pulsed output of more than 1 Watt, with pulse duration between 0.1 µs and 1 µs. In our paper we demonstrate pulses with the favorable duration for the first time in a 3 µm crystal lase

GdVO4 as a host for Thulium has several advantages for diode pumping in comparison with YAG. The absorption cross section of Thulium in GdVO4 is considerably stronger and broader than in YAG and the spectrum is shifted closer to the emission waveleng

With rising power in cw and pulsed operation erbium 3-μm lasers work their way into a variety of applications in surgery. Despite the unfavorable ratio of upper-level to lower-level lifetime cw laser operation is achieved in fluoride host materials
