Specifications

| Product Introduction

Nd:YVO₄ crystal (Nd:YVOHour) Is a commercial Laser Crystal with excellent performance, used to manufacture laser diode pumps, especially low-and medium-power Laser Source.Compared with Nd:YAG, Nd:YVOHourIt has a higher Absorption coefficient and a larger stimulated emission cross section for pump light.Laser diode-pumped Nd:YVOHourThe crystal is used in conjunction with Nonlinearity crystals such as LBO, BBO, KTP, etc., to achieve better frequency doubling conversion efficiency, and can be made into solid-state Laser Source with output Near Infrared (NIR), green, blue and even ultraviolet bands.Now Nd:YVO laser has been widely used in many fields, such as machinery, material processing, spectroscopy, wafer inspection, optical display, medical detection, Laser printing, data storage and so on.and Nd:YVOHourDiode-pumped solid-state Laser Source are rapidly replacing traditional Water Cooling ion-Laser Source and lamp-pumped Laser Source in the market, especially in terms of miniaturization and single longitudinal mode output.

|Nd:YVOThe RelativeAdvantages of Nd:YAG

·The pump bandwidth around 808nm is about 5 times that of Nd:YAG

(Therefore, the dependence on pump Wavelength is much lower and tends to be single-mode output)

|Nd:YVOThe Laser characteristics.

·Compared with Nd:YAG, Nd:YVOHourThe biggest advantage lies in the wider Absorption bandwidth range, with 5 times higher Absorption efficiency than Nd:YAG, and the peak Absorption Wavelength is reached at about 808nm, which can fully meet the current standard of high-power Laser diodes.

·This allows us to use smaller crystals to make more compact lasers, and means that Laser diodes can output a specific amount of energy with less power, thereby extending their service life.

·Nd:YVOHourThe Absorption bandwidth can reach 2.4 - 6.3 times that of Nd:YAG. In addition to higher pumping efficiency, it provides a larger selection space in the specification of the diode, which will reduce the Laser Source production cost.

·Nd:YVOHourIt has large stimulated emission cross sections at 1064nm and 1342nm.

·At 1064nm, the-axis directionNd:YVOHourThe stimulated emission cross section is about 4 times that of Nd:YAG, and the stimulated emission cross section at 1340nm can reach 18 times that of Nd:YAG at 1.3 m.

·ThereforeNd:YVOHourThe continuous output efficiency of the 1342nm wave is much higher than that of Nd:YAG, which makesNd:YVOHourLaser two Wavelength are more likely to maintain a strong single line excitation.

·Nd:YVOHourIt is a uniaxial crystal system that emits only linearly polarized light, so it can avoid birefringence interference during frequency doubling conversion, while Nd:YAG is a square crystal with high symmetry and does not have this characteristic.

·AlthoughNd:YVOHourThe fluorescence lifetime is about 2.7 times shorter than that of Nd:YAG, but becauseNd:YVOHourThe pump quantum efficiency is high, so a fairly high slope efficiency can still be obtained in an ideally designed optical cavity.
