Abstract

In this Letter we report on room temperature continuous wave laser operation in the red (639 nm, P-3(0) -> F-3(2)) and orange (604 nm, P-3(0) -> H-3(6)) spectral regions of Pr3+-doped LiYF4 planar waveguides fabricated by liquid phase epitaxy. Output powers of 25 and 12 mW and slope efficiencies of 5% and 6% were achieved at 639 and 604 nm, respectively, by pumping with an optically pumped semiconductor laser operating at 479.2 nm.

Tunable Pr3+:LiYF4 lasers in the green-red spectral region

Huilong Liu, Zhexian Zhao, Jing Xia, Yanfei Lu

Summary: A tunable Pr3+:LiYF4 laser was demonstrated to operate at nine different laser wavelengths using a single birefringent filter, with new wavelengths obtained and a total tuning range exceeding 190nm. Additionally, a continuous-wave simultaneous dual-wavelength laser was achieved by adjusting the rotation angle of the filter plate, showing maximum output powers at 698nm and 720nm.

Spectroscopic and laser properties of Er3+, Pr3+ co-doped LiYF4 crystal

Zhengda Sun, Feifei Wang, Haiping Xia, Hongkun Nie, Kejian Yang, Ruihua Wang, Jingliang He, Baitao Zhang

Summary: This study investigated the absorption and fluorescence spectra of Er3+ and Pr3+ co-doped LiYF4 crystals, showing that Pr3+ co-doping effectively enhances the mid-infrared transition of Er3+. Using Judd-Ofelt theory, the stimulated emission cross section was calculated and a diode-end-pumped Er,Pr:YLF laser operating at 2659 nm was successfully realized for the first time. This laser showed promising potential for 2.7 μm laser generation.

Continuous broadband tunable Pr3+:LiYF4 laser in the near-infrared spectral range

Zhuang Li, Shaoqiang Zheng, Zhiping Cai, Run Fang, Bo Xiao, Huiying Xu

Summary: We present a continuously broadband tunable Pr3+:LiYF4 (Pr:YLF) laser in the near-infrared spectra range pumped by InGaN laser diodes (LDs). The upper energy level of the laser utilizes composite energy levels (3P0,1,1I6). The laser achieves a continuous tuning range of 855 nm to 931 nm (width of 77 nm) for pi-polarization and 850 nm to 912 nm (width of 63 nm) for sigma-polarization, with absorbed pumped power of approximately 9 W at 444 nm. The laser also demonstrates the highest tuning power and widest continuous tuning range to date, with the ability to generate thirteen new wavelengths in the Pr:YLF crystal.

Hao Ren, Hongyuan Li, Yong Zou, Hengyang Deng, Ziming Peng, Tao Ma, Shoujun Ding

Summary: In this study, a 2 at.% Pr3+ doped oxide crystal, Pr:NaGd(MoO4)2 crystal, was successfully grown and its structure and spectroscopic properties were characterized. The crystal showed strong absorption at 450 nm and emitted the strongest fluorescence at 652 nm under 450 nm excitation. These results indicate that Pr:NaGd(MoO4)2 crystal has great potential as a material for InGaN-based LD pumped orange-red lasers.

Optical vortex lattice mode generation from a diode-pumped Pr3+:LiYF4 laser

A. Srinivasa Rao, Taku Miike, Katsuhiko Miyamoto, Takashige Omatsu

Summary: This study presents the direct generation of optical vortex lattice (OVL) modes from a diode-pumped Pr:YLF laser by utilizing off-axis and defocused pumping geometries, resulting in more than 40 phase singularities. The observed OVL modes are well explained by a theoretical analysis based on the superposition of Hermite-Gaussian modes. The study also discusses the intracavity frequency doubling of the OVL modes and suggests potential applications in fundamental optical science and advanced material engineering.
