TITLE: Optimising Crop Yield and Agricultural Resources with Precision Laser Sensing Laser sources possessing broad emission bandwidths: Wavelength tunable in a wide range Different pulse durations (ns/ps/fs) Benefit to many technological and scientific studies Space-borne and Air-borne remote sensing: 3-D mapping of atmospheric species and physical attributes Spectral indicators of Earth features High precision ground topography Valuable source for understanding the atmospheric science Health of the Earth vegetation and ecological system

TITLE: Optimising Crop Yield and Agricultural Resources with Precision Laser Sensing Cr-doped chrysoberyl (Alexandrite) is an attractive vibronic solid-state laser gain medium with superior optical and thermo-mechanical properties Broad tunability range: ~700 nm – 850 nm Relatively higher fracture resistance (x5 Nd:YAG) Relatively higher thermal conductivity (23 Wm-1K-1) (x2 Nd:YAG and x5 Cr doped colquiriites) Relatively longer upper-state lifetime (~260 μs) (Ti:S – 3 μs) at room-temperature (provides a good energy storage potential for Q-switched operation) Remote sensing of vegetation: (~700 nm – 750 nm) for chlorophyll Changes in this spectral band are well-known as indicators of plant health Very important for a vegetation lidar to cover this red-edge band range Optical parametric conversion: Higher complexity & cost and lower reliability & efficiency

TITLE: Optimising Crop Yield and Agricultural Resources with Precision Laser Sensing World-first wavelength tunable passive Q-switched direct diode-pumped Alexandrite laser Ufuk Parali, Gabrielle Thomas, Ara Minassian, Xin Sheng, Michael J. Damzen, “Wavelength tunable passively Q-switched Alexandrite laser with direct diode-pumping at 635 nm ”, Proc. of the 5th Int. Conf. on Photonics, Optics and Laser Technology, pages 82-89, ISBN: 978-989-758-223-3, March 2017.

Conclusions This work demonstrated experimentally the world-first wavelength tunable passive Q-switched (utilizing SESAM) TEM00 mode operation of Alexandrite laser with direct red diode-pumping (AlGaInP) at 635 nm. Results obtained in this study pave the way for further development, optimization and power scaling of this new generation tunable diode-pumped passive Q-switched (and also potentially for passive mode-locked) Alexandrite laser. Potential to become an attractive source for adressing the requirements of many near-future crucial scientific, medical and game-changing industrial applications. Attractive source for next generation space-borne/air-borne remote sensing applications, especially for the vegetation lidar systems !!! Enabling Technology New Opportunities
