“…In comparison with edge emitting laser diodes, VCSELs have low threshold current, 2 low fabrication cost, and wavelength stability with temperature variation. 3 The latter feature of VCSELs results in a simplified cooling system of laser pumps as well as increased laser reliability when operating at high temperatures. In addition, having a circular beam shape, VCSELs can become efficient pump sources due to the uniform excitation of a gain medium.…”

In this work longitudinal pumping of a continuous wave (CW) Nd:YVO 4 laser by high power VCSEL modules was numerically studied. Two VCSEL pump modules (6 W and 15 W) were compared. The maximum output power from a Nd:YVO 4 crystal using these pump modules was calculated to be 2.5 W and 6 W, respectively, using a 10 % output coupler. The slope and optical-to-optical efficiencies in both cases were around 47% and 40%, respectively. The performance of Nd:YVO 4 crystal was found to be better than that of Nd:YAG crystal. Our numerical results indicate that VCSELs can serve as efficient pump sources for the end-pumped CW Nd:YVO 4 lasers.

“…Comparing with the edge-emitting laser stacks, VCSELs have high efficiency (>40%). 12 The narrow linewidth of VCSEL (1 nm, full width at half-maximum (FWHM)) enables strong and resonate absorption of Nd: YAG crystal. 13 These two factors guarantee a high overall battery efficiency of the lasers.…”

Development of a compact verticalcavity surface-emitting laser end-pumped actively Q-switched laser for laser-induced breakdown spectroscopy" (2016 This paper reports the development of a compact and portable actively Q-switched Nd:YAG laser and its applications in laser-induced breakdown spectroscopy (LIBS). The laser was end-pumped by a vertical-cavity surface-emitting laser (VCSEL). The cavity lases at a wavelength of 1064 nm and produced pulses of 16 ns with a maximum pulse energy of 12.9 mJ. The laser exhibits a reliable performance in terms of pulse-to-pulse stability and timing jitter. The LIBS experiments were carried out using this laser on NIST standard alloy samples. Shot-to-shot LIBS signal stability, crater profile, time evolution of emission spectra, plasma electron density and temperature, and limits of detection were studied and reported in this paper. The test results demonstrate that the VCSEL-pumped solid-state laser is an effective and compact laser tool for laser remote sensing applications. C 2016 AIP Publishing LLC.[http://dx

“…If implemented properly, these diode lasers have the potential to act as a miniaturized end pump source for q-switched lasers. This technology has yet to develop for LI applications, however it has been applied as a pumping mechanism for end pumped, Nd:YAG solid-state lasers [47,48,49].…”

“…As previously discussed in Section 3.4.1.3, VCSEL technology has developed to the point where it can efficiently act as a pumping source for end-pumped passively q-switched Nd:YAG lasers [47,48,49]. This pumping mechanism is presently considered to be the best means of pumping a laser with unique spatial requirements in harsh conditions.…”

A study was conducted in order to evaluate the external thermal and vibrational effects on the operation of a laser ignition system for internal combustion (IC) engine applications. West Virginia University (WVU) in conjunction with the National Energy Technology Laboratory (NETL) have constructed a prototype laser spark plug which has been designed to mount directly onto the head of a natural gas engine for the purpose of igniting an air/fuel (A/F) mixture in the engine's combustion chamber. To be considered as a viable replacement for the conventional electrode-based ignition system, integrity, durability and reliability must be justified. Thermal and oscillatory perturbations induced upon the ignition system are major influences that affect laser spark plug (LSP) operation and, therefore, quantifying these effects is necessary to further the advancement and development of this technology. vii
