Compact corner-pumped Nd:YAG/YAG composite slab 1319 nm/1338 nm laser

Abstract

A corner-pumped type is a new pumping type in the diode-pumped solid-state lasers, which has the advantages of high pump efficiency and favorable pump uniformity. A corner-pumped Nd:YAG/YAG composite slab continuous-wave 1319 nm/1338 nm dual-wavelength laser is first demonstrated in this paper. When the cavity length is 25 mm, the maximal output power is up to 7.62 W with a slope efficiency of 16.6% and an optical-to-optical conversion efficiency of 17%. The corresponding spectral line widths of 1319 nm laser and 1338 nm laser are 0.11 and 0.1 nm, respectively. The short-term instability of the output power is better than 1% when the pumping power is 39.5 W. The experimental results show that a corner-pumped type is a kind of feasible schedules in the design of diode-pumped solid-state 1.3 μm lasers with low or medium output powers.

“…In this work, we report, for the first time, the results of intracavity second har monic generation in a GdCOB crystal for the type I phase matching and performed with a 880 nm diode end pumped CW Nd:Y 0.36 Gd 0.64 VO 4 laser. 1 The article is published in the original.…”

“…Lasers emitting in the visible range are useful in many fields, such as medicine, lithography, communi cations, display or biology [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. In past few years, new solid sate lasers were designed to enlarge the panel of wavelengths [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”

Synchronized generation of 1534 and 1572 nm by the mixed optical parameter oscillation

“…The frequency conversions based on the nonlinear crystals have been validated as efficient approaches for the multiple-wavelength emission, such as the cascaded second-order χ (2) [8], thirdorder χ (3) [9], and χ (2) + χ (3) conversion processes [10]. However, these conversion processes have a common disadvantage that the subsequent conversion is always based on the completion of the former process.…”

“…In addition, through frequency conversion technology, the red light of frequency dou bling and the 1.5 µm eye safe light of stimulate Raman scattering (SRS) can be generated [1][2][3][4][5][6][7][8][9][10][11]. It is well known that 1.3 µm wavelength can be obtained by the 4 F 3/2 -4 I 13/2 transition of Nd 3+ doped materials such as Nd:YAG, Nd:YLF, and Nd:YVO 4 [12][13][14][15][16][17]. Nd:YAG crystals have been the most widely used solid state laser mediums due to their excellent optical and mechanical properties.…”
