“…Previously, diode lasers of this type were used to generate 1.5 W and 1.8 W of green light in single-pass, single-crystal SHG [16,17,18]. These results comprised the highest SHG powers from diode lasers prior to this work.…”

light from a tapered laser diode, while avoiding significant thermal effects. Besides constituting the highest SH power yet achieved using a laser diode, this demonstrates that the concept successfully combines the high efficiency of the first stage with the good power handling properties of the subsequent stages. The concept is generally applicable and can be expanded with more stages to obtain even higher efficiency, and extends also to other combinations of nonlinear media suitable for other wavelengths.

“…This type of technique has also been used to generate picosecond pulses into the orange−to−red spectral region (600-627 nm), using a tunable QD mode−locked external−cavity laser [73], with maximum efficiency of 4.5%. The access to the visible spectral region, particularly in the yellow range, would be useful for a range of biomedical applications, most notably in ophthalmology [74].…”

Wavelength−tunable semiconductor quantum−dot lasers have achieved impressive performance in terms of high−power, broad tunability, low threshold current, as well as broadly tunable generation of ultrashort pulses. InAs/GaAs quantum−dot−based lasers in particular have demonstrated significant versatility and promise for a range of applications in many areas such as biological imaging, optical fiber communications, spectroscopy, THz radiation generation and frequency doubling into the visible region. In this review, we cover the progress made towards the development of broadly−tunable quantum−dot edge−emitting lasers, particularly in the spectral region between 1.0-1.3 µm. This review discusses the strategies developed towards achieving lower threshold current, extending the tunability range and scaling the output power, covering achievements in both continuous wave and mode−locked InAs/GaAs quantum−dot lasers. We also highlight a number of applications which have benefitted from these advances, as well as emerging new directions for further development of broadly−tunable quantum−dot lasers.

“…Frequency doubling of such lasers has been demonstrated at different wavelength regions [12][13][14][15]. Recently, single-pass SHG of tapered diode lasers with an embedded distributed Bragg reflector (DBR) has resulted in more than 1.5 W of visible light at 488 nm and 532 nm and in a cascade of two nonlinear crystals as much as 3.5 W was demonstrated [16].…”
