“…Moreover, higher output powers are achieved as a result of the straightforward power scalability of the disk laser concept. 7 To date, above 2-lm wavelength single-frequency SDLs with kHz linewidths have been demonstrated at an emission wavelength of 2.3 lm with 5 mW of output power 8 and, using active stabilization, 200 mW of output power at the same wavelength. 9 The narrowest linewidth of <10 kHz reported so far for this wavelength range was achieved at 2.0 lm with an output power of 100 mW.…”

We report on an optically pumped single-mode GaSb-based semiconductor disk laser (SDL) emitting at 2.05 μm at an output power of 960 mW (1100 mW) with a side-mode suppression of better than 30 dB (20 dB). A linewidth of 60 kHz (sampling time: 100 μs) was measured at an output power of 960 mW. This improvement in output power over previous reports, which was achieved via a careful design of the SDL cavity paying close attention to the spatial overlap between cavity mode and pump spot, makes this class of SDL particularly attractive for remote sensing and optical free-space communication.

“…The gain structure is mounted on a water-cooled temperature-controlled copper block. Neither the gain nor the SESAM structure has been processed, limiting the maximum average output power [17]. All components are directly mounted on a single Invar plate to reduce misalignment due to vibrations or thermal drift and thus improve long-term mode-locked stability.…”

Abstract-We report supercontinuum generation using a mode-locked VECSEL emitting 400-fs pulses at a 3-GHz repetition rate, amplified with a cascaded ytterbium-doped fiber amplifier system up to 40 W of average power. The pulses were then recompressed to their original duration via a high throughput transmission grating compressor, and used to generate supercontinuum in two samples of photonic crystal fiber (PCF); an all-normal dispersion PCF, and a PCF with a zero dispersion wavelength of 1040 nm, creating 20 dB spectral bandwidths of 200 nm and 280 nm respectively.

“…In this way, we have demonstrated high output powers of up to the order of 100W around 1 m using the thinning approach, and wide tunability (in terms of device composition) at 1-10W output power using heat spreading. 2 Through the European Union project VERTIGO, we have also developed widely tunable ( 150nm) and high-power (6W) (AlGaIn)(AsSb)-based SDLs grown on GaSb substrates in the 1.9-2.8 m wavelength region. 3 We initially designed these sources for eye-safe, long-range free-space optical communications systems, and we are now extending them to highly compact solid-state laser pumping of Cr 2C :ZnSe (chromiumdoped zinc selenide) lasers 4 providing stable watt-level output powers (see Figure 2).…”

The mid-IR spectral region is increasingly important for a wide range of applications in the industrial, environmental, security, medical, and scientific sectors. Examples include sensing and spectroscopy; biomedical imaging and tissue processing; industrial monitoring and process control; materials processing; and trace molecular detection for environmental study and security. These applications represent a vast array of different source requirements in tunability and energy. But all are limited in some way by current laser source format and availability. A number of approaches have been effected to address these limitations, such as lead-salt lasers, high-power diode-pumped solid-state lasers, quantum cascade lasers (QCLs), and optical parametric oscillators. Many of these systems require multistage resonators, complex growth and processing, or cryogenic cooling to achieve significant performance and/or tunability. The most significant developments have been, and so far continue to be, in QCLs. For instance, in the GaInAs/AlInAs-on-InP (gallium indium arsenide/aluminum indium arsenide on indium phosphide) material system, an impressive wavelength coverage over 3.5-12 m has been demonstrated, with output powers in excess of 1W over most of this range. Current research and development challenges seek to extend the spectral coverage to shorter wavelengths while increasing power efficiency. Optically pumped semiconductor disk lasers (SDLs) 1-3 based on InGaAs/(Al)GaAs and (AlGaIn)(AsSb, arsenic antimonide), emitting in the 1 and 2 m spectral ranges, respectively, are among the powerful technologies to have emerged. These lasers provide high beam quality, continuous-wave outputs with
