Abstract We demonstrate a compact, high efficiency and widely tunable intracavity singly resonant optical parametric oscillator (IC-OPO) based on multichannel periodically poled lithium niobate (PPLN). The IC-OPO is composed of 808 nm pump laser diode (LD), Nd:YVO 4 linear OPO. continuous-wave (CW) mid-infrared (MIR) output from 2.25 to 4.79 μm. maximum power exceeds 1.08 W at 3.189 μm 9.1 LD the conversion 11.88%. also build up prototype with volume 145 × 85 42.5 mm 3 its total weight less...
Traditional transit systems are usually composed of fixed routes and stops, which suitable in densely populated areas. This paper presents a reformulation the flexible model developed by Nourbakhsh Ouyang (2012) to adapt it many low demand cities world, especially those characterized radial street patterns. Unlike traditional ones, buses proposed network allowed traverse predetermined service area their precise trajectories hinge on exact locations passengers. To identify optimal topology...
In order to predict sea surface temperature (SST), combined with the genetic algorithm and least-squares method, a GM(1,1|sin) power model prediction method based on similarity deviation is proposed. We first data of two consecutive years into new time series, analyzed previous year, obtained most similar year corresponding series. Then, we established SST. validation, predicted monthly average SST from 2016 2020 1985 2015, 2016, 2017, 2018, 2019. The validation results showed that maximum...

We demonstrate a high-power, wavelength tunable mid-infrared laser with high-precision power attenuator. The output is 5.1W at 3.8μm, achieved by an optical parametric oscillator (OPO) based on multichannel periodically-poled lithium niobate (PPLN). repetition frequency 10kHz, and the pulse width 69ns. from 3.708μm to 4.142μm. High-precision control attenuator obtained, accuracy of 0.2dB 0~27dB.
