All-solid-state cw sodium D_2 resonance radiation based on intracavity frequency-doubled self-Raman laser operation in double-end diffusion-bonded Nd^3+:LuVO_4 crystal

Abstract

We report for the first time (to our knowledge) cw orange-yellow emission at 589 nm from a compact double-end diffusion-bonded Nd(3+):LuVO(4) self-Raman laser with intracavity frequency doubling in LiB(3)O(5), pumped by an 880 nm diode laser. A 3.5 W cw orange-yellow emission with an overall diode-to-visible conversion efficiency of 13.3% is achieved through the use of an 18-mm-long double-ended diffusion-bonded Nd(3+):LuVO(4) crystal. The M(2) factors are 1.35 and 1.74 in both the horizontal and vertical dimensions, respectively.

Continuous-Wave Nd:YVO_4 self-Raman lasers operating at 1109nm, 1158nm and 1231nm

“…This extended coverage benefits many applications especially when SRS is used in conjunction with Second Harmonic Generation (SHG) or Sum Frequency Generation (SFG) impacting medicine (retinal laser photocoagulation) [3], laser projection displays, and remote sensing (bathymetry or underwater detection) [4]. All-solid-state continuous-wave (CW) Raman lasers are widely recognized as a practical and efficient way to produce laser outputs in the near infrared, visible and ultraviolet wavebands [5][6][7][8][9][10][11]. Typically, intracavity Raman lasers feature a separate Raman active crystal inserted inside a laser resonator.…”

Diode-pumped CW frequency-doubled Nd:CNGG-BiBO blue laser at 468 nm

“…These past few years, there has been extensive research to find more efficient and more compact lasers. Thus, new lasers were designed to reach new wavelengths, for example in the yellow range [1][2][3][4][5], or to improve sources already used, as in the blue range [6][7][8][9]. Diode-pumped solidstate (DPSS) lasers operating in the blue spectral range have a large number of applications ranging from highdensity optical data storage to phototherapy and medical diagnostics.…”

“…Compact diode-pumped neodymium-doped crystal lasers operating in the infrared [1][2][3] and visible spectral regions have wide applications in the fields of industry, defense, medical treatment, and scientific research [4][5][6][7][8]. The laser crystal is one of the most important components of a diode-pumped solid-state laser.…”
