“…For more compact set-ups, it may be convenient to pump through the • DBR after removal of the substrate. 29 The close proximity achieved in this case has enabled effi cient optical pumping even without pumpcoupling optics. 30 Due to the broad absorption spectra of the semiconductor materials the • exact pump wavelength is not critical, although longer wavelengths are desirable to reduce the quantum defect.…”

“…Multiple pump beams incident on a single pump spot from different directions can be used to excite a VECSEL. In an analogy with diode-pumped solidstate lasers [13,14], an optical end-pumping scheme has also been used with VECSELs [155][156][157][158]. In this configuration, pump light enters through a transparent heat sink on one side of the OPS chip, and laser output is taken from the other side of the chip.…”

Since its invention and demonstration in 1960, several types of laser have been developed, such as solid-state, semiconductor, gas, excimer, and dye lasers [1]. Today, lasers are used in a wide range of important applications, particularly in optical fiber communication, optical digital recording (CD, DVD, and Blu-ray), laser materials processing, biology and medicine, spectroscopy, imaging, entertainment, and many others. A number of properties enable the application of lasers in these diverse areas, each application requiring a particular combination of these properties. Some of the most important laser properties are laser emission wavelength; output optical power; method of laser excitation, whether by optical pumping or electrical current injection; laser power consumption and efficiency; high-speed modulation or short pulse generation ability; wavelength tunability; output beam quality; device size; and so on. Thus, optical fiber communication [2], a major application that enables modern Internet, commonly requires lasers with emission wavelengths in the 1.55 mm lowloss band of glass fibers and with single-transverse mode output beams for coupling into single-mode optical fibers. Typically, a given laser type excels in some of these properties, while exhibiting shortcomings in others. For example, by using different material compositions and structures, the most widely used semiconductor diode laser [3][4][5][6][7][8][9][10][11][12] can cover a wide range of wavelengths from the ultraviolet (UV) to the mid-IR, can be advantageously driven by diode current injection, and is very compact and efficient. However, the good beam quality, that is, single-transverse mode nearcircular beam operation, can be typically achieved in semiconductor lasers only for output powers below 1 W. Much higher power levels are achievable from semiconductor lasers only with large aspect ratio highly multimoded poor quality optical beams. On the other hand, the solid-state lasers [13,14], including fiber lasers [15], can emit hundreds of watts of output power with excellent beam quality, however, their emission wavelengths are restricted to discrete values of electronic transitions in ions, such as the classic 1064 nm wavelength of the Nd:YAG laser, making them Semiconductor Disk Lasers.

“…This can be alleviated to a certain extent, with extra pump optics and/or cavity ar-rangements. Enhancement of the pump brightness can also be achieved by pumping the OPSDL through the substrate and DBR if a suitable material combination that does not absorb the pump are used (post processing can be used to remove the substrate to facilitate direct pumping through the DBR [50]). Alternative cavity arrangements which involve coating the intracavity heatspreader to form a microchip geometry [51] are also possible and will be discussed in more detail later.…”

A review on the recent developments in the field of long-wavelength (λ > 1.2 μm) high-brightness opticallypumped semiconductor disk lasers (OPSDLs) is presented. As thermal effects have such a crucial impact on the laser performance particular emphasis is given to modelling the thermal behaviour and optimisation of the heat-sinking. Selected OPSDL devices, realized in different III-V and IV-VI semiconductor material systems, with corresponding emission wavelengths between 1.2 μm and 5.3 μm are presented. Specific applications in this broad spectral range are addressed and methods to obtain high output power are discussed in terms of the underlying material properties and device operating principles.Schematic OPSDL setup, two-dimensional far-field profile of an emitted beam and typical emission spectrum of an (AlGaIn)(AsSb)-based OPSDL.
