“…For instance, how to produce the pulsed laser with high peak power is an important question for super-resolution bio-imaging microscopy and advanced materials processing91011. Among all the methods, the passive Q-switching based on saturable absorption is more promising to produce such high power output1213141516. However, the intra-cavity intensity of the waveguide laser is commonly lower than several megawatts per square centimeter (MW/cm 2 ), which is below the saturation intensity of most saturable absorbers.…”

How to enhance the optical nonlinearity of saturable absorption materials is an important question to improve the functionality of various applications ranging from the high power laser to photonic computational devices. We demonstrate the saturable absorption (SA) of VO2 film attributed to the large difference of optical nonlinearities between the two states of the phase-transition materials (VO2). Such VO2 film demonstrated significantly improved performance with saturation intensity higher than other existing ultrathin saturable absorbers by 3 orders due to its unique nonlinear optical mechanisms in the ultrafast phase change process. Owing to this feature, a Q-switched pulsed laser was fabricated in a waveguide platform, which is the first time to achieve picosecond pulse duration and maintain high peak power. Furthermore, the emission of this VO2 waveguide laser can be flexibly switched between the continuous-wave (CW) and pulsed operation regimes by tuning the temperature of the VO2 film, which enables VO2-based miniature laser devices with unique and versatile functions.

The International Year of Light 2015 was a landmark for the laser and optics community pointing the way to a bright future for humanity and the environment. It is with great satisfaction that Laser Physics and Laser Physics Letters have published many notable articles that have contributed to the development of light-based technologies and breakthroughs in photonics. In recognition of their high quality, we present a selection of some of the most popular articles published by Laser Physics and Laser Physics Letters throughout 2015, all of which are believed to have the potential to make a high impact on future research directions. Those chosen are recognised for their high-interest with readers and importance in the field, providing a snapshot of the broad subject coverage and international make-up of both journals.Starting this year, we will be recognising and announcing annual highlights of a previous year for both journals. We hope that you find these highlights useful and look forward to publishing more cutting-edge work in the year ahead.Summary of the highlights articles: Physics of lasers• • Experimental investigation of the light shift effect in an optical-magnetic double resonance system-an experimental scheme for studying the light shift effect in an optical magnetic double resonance system by using 4 He atoms is demonstrated [3]. • Enhanced random lasing from a colloidal CdSe quantum dot-Rh6G system-randomlaser action in a system where optical amplification is provided by colloidal CdSe quantum dots triggered by the emission from Rhodamine 6 G is reported [4].• Ultra-short pulse generation in the hybridly mode-locked erbium-doped all-fiber ring laser with a distributed polarizer-ultra-short pulse generation in a dispersion-managed erbium-doped all-fiber ring laser hybridly mode-locked with boron nitride-doped singlewalled carbon nanotubes, in co-action with a nonlinear polarization evolution in the ring cavity with a distributed polarizer, is reported for the first time [5].• Analysis of pump excited state absorption and its impact on laser efficiency-a model to quantify the effect of excited state absorption at the pump wavelength on laser efficiency, threshold and heating is developed [6].
