Visible pulsed lasers are required for many applications, for example in biomedical imaging [1] and STED microscopy [2]. Such applications often have stringent requirements on the wavelength and pulse duration, which are not directly available from typical solid-state sources. One method of accessing these wavelengths is to use Raman lasers, with diamond being an excellent Raman laser material [3,...
Semiconductor disk lasers (SDLs) are capable of several Watts of continuous-wave (CW) output power in a single transverse mode, with emission demonstrated from the visible to the mid-infrared. Moreover, their highfinesse extended cavities allow the incorporation of intracavity nonlinear crystals to convert to wavelengths where direct emission of SDLs is non-trivial. SDLs based on InGaAs QWs exhibit...
During the recent years, the wavelength coverage of optically-pumped vertical external-cavity surface-emitting lasers (VECSELs) has expanded significantly and currently reaches from the UV to mid-IR (although not without gaps). This progress has been fuelled by the ability to tailor the VECSELs emission wavelength via bandgap engineering and by the capability to deploy different kinds of semiconductor...
<para> We report a mode-locked antimonide-based semiconductor disk laser operating at 2 m, synchronously pumped with a pulsed source incorporating a 1.57- m diode laser, a lithium niobate intensity modulator, and an erbium-doped fiber amplifier. The method for producing the pump signal utilizes commercially available telecom components and allows for convenient selection of the mode-locking...
