Cryogenic cooling for high power laser amplifiers

open access: yesEPJ Web of Conferences, 2013
Using DPSSL (Diode Pumped Solid State Lasers) as pumping technology, PW-class lasers with enhanced repetition rates are developed. Each of the Yb YAG amplifiers will be diode-pumped at a wavelength of 940 nm.

Charge and exciton dynamics of OLEDs under high voltage nanosecond pulse: towards injection lasing

open access: yesNature Communications, 2020
Though efforts toward electrically-pumped lasers based on simple organic light-emitting diode (OLED) structures have been reported, a comprehensive model is needed to elucidate key optoelectronic processes.

Selectable Dual-Wavelength Actively Q-Switched Laser by Monolithic Electro-Optic Periodically Poled Lithium Niobate Bragg Modulator

open access: yesIEEE Photonics Journal, 2013
A novel dual-wavelength actively Q-switched laser by a cascaded electrooptic periodically poled lithium niobate (PPLN) Bragg modulator has been developed. Two PPLN Bragg modulators with grating period Λ1 = 20.3 (EPBM1) and Λ2 = 25.7 μ

High-Power Continuous-Wave Directly-Diode-Pumped Fiber Raman Lasers

open access: yes, 2015
We describe novel fiber Raman lasers pumped directly by spectrally combined high power multimode laser diodes at ~975 nm and emitting at ~1019 nm. With a commercial multimode graded-index fiber, we reached 20 W of laser output power with a record slope ...

Randomly polarised beam produced by magnetooptically Q-switched laser

open access: yesScientific Reports, 2017
Diode-pumped solid-state micro lasers are compact (centimetre-scale), highly stable, and efficient. Previously, we reported Q-switched lasers incorporating rare-earth substituted iron garnet (RIG) film. Here, the first demonstration of the magnetooptical

Diode-pumped, Q-switched Alexandrite laser as emitter for general purpose atmospheric Lidar systems [PDF]

open access: yesEPJ Web of Conferences
We present design and performance of four prototypes of narrow-bandwidth emitters based on diode-pumped Alexandrite lasers for atmospheric Doppler-Mie, -Rayleigh and -resonance lidar systems. Furthermore, lab results for efficient frequency-doubling into
