photochemical Gas Lasers and hybrid solid Gas blue green femtosecond systems
Progress in Quantum Electronics, 2012Co-Authors: L D Mikheev, V I Tcheremiskine, O Uteza, M SentisAbstract:Abstract The review summarizes milestones and major breakthrough results obtained in the course of the development of a photochemical method applied to optical excitation of Gas Lasers on electronic molecular transitions by radiation from such unconventional pump sources as high-temperature electrical discharges and strong shock waves in Gas. It also describes principles and techniques applied in hybrid (solid/Gas) high-intensity laser systems emitting in the blue-green spectral region, and discusses wavelength scaling of laser–matter interaction by the example of laser wake-field acceleration (LWFA), high-order harmonic generation (HHG) and “water window” soft X-ray Lasers. One of the most significant results of the photochemical method development consists in emerging broad bandwidth Lasers (XeF(C–A), Xe2Cl, and Kr2F) operating in the blue-green spectral range, which have potential for amplification of ultra-short (down to 10 fs) optical pulses towards the Petawatt peak power level. The main goal of this review is to argue that the active media of these Lasers may provide a basis for the development of fs systems generating super-intense ultrashort laser pulses in the visible spectral range. Some specific hybrid schemes, comprising solid state front-ends and photodissociation XeF(C–A) power boosting amplifiers, are described. They are now under development at the Lasers Plasmas and Photonic Processes (LP3) Laboratory (Marseille, France), the P.N. Lebedev Physical Institute (Moscow, Russia) and the Institute of High-Current Electronics (Tomsk, Russia) with the aim of conducting proof-of-principle experiments. Some consequences of the visible-wavelength laser field interaction with matter are also surveyed to demonstrate advantages of short driver wavelength in the considered examples. One of the most important consequences is the possibility of coherent soft X-ray generation within the “water window” spectral range with the use of short wavelength driver pulses to pump a recombination laser.

investigation of dual wavelength pump schemes for optically pumped rare Gas Lasers
Optics Express, 2020Co-Authors: Pengfei Sun, Duluo Zuo, Xu Wang, Jiande Han, Michael C HeavenAbstract:Optically pumped rare Gas Lasers (OPRGLs) have shown great potential to generate high energy laser radiation with high beam quality. As an alternative to the diode-pumped alkali vapor Lasers (DPALs), they have similar working principles and characteristics, but OPRGLs have the advantage that the gain medium is chemically inert and is appropriate for closed-cycle operation. One of the challenges OPRGLs are faced with is the bottleneck caused by the slow 1s4-1s5 collisional relaxations at room temperature. A 1s4-2p10 dual-wavelength pump method had been proposed to transfer the populations pooled on the 1s4 level to the lasing cycle using a steady-state laser model. We explored this method further through 1s4-2p8 and 1s4-2p7 dual-wavelength pump schemes. The enhancement efficiencies at room temperature for a repetitively pulsed discharge, CW dual-wavelength pump system were examined using a dynamic model, and an experiment with a pulsed secondary pump was conducted for qualitative evaluations.

simulations for transversely diode pumped metastable rare Gas Lasers
Journal of The Optical Society of America B-optical Physics, 2017Co-Authors: Jun Gao, Pengfei Sun, Zhifan Zhang, Xinbing Wang, Duluo ZuoAbstract:The transverse pumping geometry simplifies the laser system design by separating pump and laser beams and providing space for multiple diode laser pump sources with poor beam quality. A transverse pumping double-pass model for metastable rare Gas Lasers is presented in this paper, in which some intra-cavity information can be obtained. The comparison with Yang’s longitudinally pumped calculation results demonstrated the validity of our model. Several important factors having influence on optical conversion efficiency are simulated and discussed. Simulation of the effects of the required plasma size in transverse pumping model shows that a small size of 0.3 cm×10 cm×10 cm is capable of emitting 9 kW with an optical conversion efficiency over 55% and a megawatt-class output would only need an active medium of several liters if the metastable atoms concentration reaches 3×1013 cm−3.
