“…Recent developments in chemical vapour deposition growth have led to material with low birefringence and low absorption through the minimisation of the dislocation density and nitrogen impurities respectively [20,21]. This has made the intracavity use of diamond in solid-state lasers more practical -as a heat spreader [28,29] and in Raman lasers [11,[15][16][17][18].…”

“…In this paper, the use of CVD-grown, low-loss, low-birefringence diamond as a Raman medium in a CW Nd:YVO 4 disk laser is reported. By improving the thermal management of the pump laser gain medium (Nd:YVO 4 ) using a diamond heat spreader [17], and using a lower loss diamond as the Raman laser medium, CW output powers of 1.6W at the Raman laser wavelength (1240nm) were achieved, eight times higher than previously reported [9]. The next section describes the diamond sample.…”

Low-birefringence ( n<2x10 6 ), low-loss (absorption coefficient <0.006cm1 at 1064nm), single-crystal, synthetic diamond has been exploited in a CW Raman laser. The diamond Raman laser was intracavity pumped within a Nd:YVO 4 laser. At the Raman laser wavelength of 1240nm, CW output powers of 1.6W and a slope efficiency with respect to the absorbed diode-laser pump power (at 808nm) of ~18% were measured. In quasi-CW operation, maximum on-time output powers of 2.8W (slope efficiency ~24%) were observed, resulting in an absorbed diode-laser pump power to the Raman laser output power conversion efficiency of 13%.

“…Different thermal management techniques including thin device or heat spreader approaches have been a subject of thermal modelling [3][4][5][6][7]. Moreover, various factors which influence the temperature increase within laser vol− ume such as: pumping−beam properties (e. g., power [5,7], diameter [3,5,8], wavelength [5,6,8], spatial profile [5]), as well as thermal conductivity or thickness of heat spreader [3][4][5][6][7]9], window [5] and DBR mirror layers [7] have been investigated. In this paper the complex comparative analysis of different VECSEL configurations (e.g., as−grown, thin device, heat spreader approaches) has been presented in form of so−called 'thermal maps' which enable determining the maximum temperature at specified pumping conditions in a quick and simple way, so they can be very useful, espe− cially at VECSEL designing.…”

Different methods used to reduce temperature increase within the active region of vertical-external-cavity surface-emitting lasers (VECSELs) are described and compared with the aid of the self-consistent thermal finite-element method. Simulations have been carried out for the GaInNAs/GaAs multiple-quantum-well (MQW) VECSEL operating at room temperature at 1.31 μm. Main results are presented in form of ‘thermal maps’ which can be simply used to determine maximal temperature of different structures at specified pumping conditions. It has been found that these maps are also appropriate for some other GaAs-based VECSELs and can be very helpful especially during structure designing. Moreover, convective and thermal radiation heat transfer from laser walls has been investigated.
