compact 0 56 petawatt laser system based on optical parametric chirped pulse amplification in kd p crystals
Laser Physics Letters, 2007Co-Authors: V V Lozhkarev, G I Freidman, V N Ginzburg, E V Katin, E A Khazanov, A V Kirsanov, G A Luchinin, A N Malshakov, M A Martyanov, O PalashovAbstract:560 TW peak power has been achieved experimentally using a Cr:forsterite master oscillator at 1250 nm, a stretcher, three optical parametrical amplifiers based on KD*P crystals providing 38 J energy in the chirped pulse at 910 nm Central Wavelength, and a vacuum compressor providing 43 fs pulse duration. To our knowledge, it is a world-record OPCPA system and one of the five most powerful laser systems currently available.

Optics Express, 2006Co-Authors: V V Lozhkarev, G I Freidman, V N Ginzburg, E V Katin, E A Khazanov, A V Kirsanov, G A Luchinin, A N Malshakov, M A Martyanov, O PalashovAbstract:200 TW peak power has been achieved experimentally using a Cr:forsterite master oscillator at 1250 nm, a stretcher, three optical parametrical amplifiers based on KD*P (DKDP) crystals providing 14.5 J energy in the chirped pulse at 910 nm Central Wavelength, and a vacuum compressor. The final parametrical amplifier and the compressor are described in detail. Scaling of such architecture to multipetawatt power is discussed.

270 fs 30 w level kerr lens mode locked ho yag thin disk oscillator at 2 μm
Nonlinear Optics, 2017Co-Authors: Jinwei Zhang, Ka Fai Mak, Sebastian Grobmeyer, Dominik Bauer, Dirk Sutter, Vladimir Pervak, Ferenc Krausz, Oleg ProninAbstract:We report the first mode-locked Ho:YAG thin-disk oscillator delivering 270-fs pulses at 28 W average power and 2090 nm Central Wavelength. The output parameters constitute the shortest pulse duration and highest average power of any mode-locked oscillator around 2 µm.

diode pumped kerr lens mode locked yb lyso laser with 61fs pulse duration
Optics Express, 2014Co-Authors: Wenlong Tian, Jinwei Zhang, Zhaohua Wang, Yingnan Peng, Lihe Zheng, Jun XuAbstract:A stable diode pumped Kerr-lens mode-locked (KLM) Yb:LuYSiO5 (Yb:LYSO) laser of generating 61 fs pulses at a Central Wavelength of 1055.4 nm is experimentally demonstrated. This is, to the best of our knowledge, the first demonstration of femtosecond KLM operation in Yb:LYSO laser, and it is believed that 61 fs is the shortest pulse duration ever produced from an Yb-doped orthosilicate laser. The average output power of the mode-locked laser is 40 mW and the repetition rate is 113 MHz.

spectral properties and laser performance of ho sc 2 sio 5 crystal at room temperature
Optics Express, 2013Co-Authors: Xiaotao Yang, Lihe Zheng, Y Ding, Xuan Li, Jun XuAbstract:Holmium doped scandium silicate (Ho:SSO) bulk crystal grown by Czochralski technique is reported. The absorption cross section of 4.8 × 10−21 cm2 at pumping Wavelength 1940 nm and emission cross section of 5.56 × 10−21 cm2 at lasing Wavelength 2112 nm were calculated, respectively. Lifetime was measured to be 1.51 ms at 300 K and 0.92 ms at 77 K. Continuous-wave laser was operated by using a diode-pumped Tm:YAP laser as pump source with Central Wavelength of 1940 nm. Output power of 385 mW at 2112 nm was primarily obtained.

Optics Letters, 2015Co-Authors: V O Smolski, Peter G Schunemann, Sergey Vasilyev, S B Mirov, K L VodopyanovAbstract:Using a subharmonic optical parametric oscillator (OPO) based on orientation-patterned GaAs, we produced a broadband instantaneous output that spans 3.6–5.6 μm at 50-dB level (4.4–5.2 μm at 3 dB level), has 110 mW of average power, and is suitable for producing wideband-frequency combs in the mid-infrared. The OPO was synchronously pumped by a compact Kerr-lens mode-locked femtosecond Cr:ZnS oscillator with the Central Wavelength 2.38 μm and pulse repetition frequency 175 MHz.
