Nd:GdVO4 Crystal Neodymium Doped Gadolinium Orthovanadate
8/22/2022
Nd:GdVO4, is a promising material for diode pumped lasers. Similar to the more well-known Nd:YVO4 crystal, Nd:GdVO4 crystal also exhibits high gain, low threshold, and high absorption coefficients at pumping wavelengths. Nd:GdVO4 has the additional advantage over Nd:YVO4 of a much higher thermal conductivity. For CW lasing at 1.06 um and 1.34 um and intracavity doubling with KTP and LBO, t...

Yb:YAG Crystal Ytterbium Doped Yttrium Aluminum Garnet
8/22/2022
It is more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 0.94 μm laser output. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal i...

The Basics of Bandpass Filters
8/22/2022
The cut-off band of a filter is adjacent to both sides of the transmission band of the spectral characteristic curve, which is called Bandpass filter. Bandpass filters can be roughly divided into broadband filters and narrowband filters according to their spectral characteristics. But there is no clear boundary for this division. The two kinds of filters are usually com...

Nd:YVO4 Crystal Neodymium Doped Yttrium Orthovanadate
8/22/2022
Nd:YVO4 is one of the most promising commercially available diode pumped solid state laser materials. It has high laser induced damage threshold and good mechanical in addition to optical properties. Its large stimulated emission cross-section and high absorption of pump laser make it a right crystal for pocket laser. Nd: YVO4 can produce IR green and blue laser by using minor different s...

Information and products are one color, research and development and application are flying together
8/22/2022
Although "Applied Optics" ranks among the core journals of China's science and technology, it is not the same as media in the ordinary sense. As a "editor" of "Applied Optics", I am naturally not a "media". People" are not qualified to interview those exhibitors, and there is no interview to write about. However, as a representative who "check in and clock in" every year, I would like to talk abou...

Color Glass Filter - Blue Glass
8/22/2022
The filter is made of glass and special dyes. The blue filter can only let blue light pass through. Compared with ordinary glass,the molecular structure and refractive index of blue filter have changed, and the passage of some color light has changed. For example, when a white light passes through a blue filter, it emits a blue light, while the green light and red light are very few, and...
