The fight of eye-safe laser crystals, Yb:Er:glass and Tm:YAG, will not be a great deal a struggle as It's really a complementary romance. Each crystals supply unique strengths, as well as their variety relies on the desired software.
In length measurement, As an illustration, the higher optical get of Yb:Er:glass permits the creation of rigorous laser beams that will journey extensive distances without having considerable attenuation.
We report on a high typical power and substantial repetition amount nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Taking advantages of the diligently selected two-composite-laser-crystal configuration, the thoroughly optimized gate-open up time of acousto-optic modulator as well as the ingeniously made U-formed resonator, sizeable power and effectiveness enhancements and also exceptional method matching happen to be enabled.
Relocating on to Tm:YAG, the narrative shifts somewhat. This laser crystal encompasses a dominant emission line from the vicinity of 2.0 µm, a spread that's also considered to be eye-safe. Nonetheless, it’s the exceptional Homes associated with this certain wavelength that really established Tm:YAG aside.
For environmental monitoring, the emission wavelength of Yb:Er:glass comes into Engage in. As this wavelength coincides with the minimal-absorption window of your atmosphere, it enables the transmission of laser beams over extended distances devoid of significant absorption by atmospheric constituents. This property is invaluable in applications such as air high quality monitoring and atmospheric scientific studies.
Users that are unaware of this threat could unintentionally expose on their own to harmful laser radiation.
This facet of large optical get don't just allows for a robust performance but will also encourages effectiveness. The less Vitality necessary to deliver a potent laser beam, the more source-efficient the laser system results in being.
Crystalline Raman lasers using tungstate and molybdate crystals let producing compact trusted and impressive laser units. Nonlinear and optical Homes, laser operation of Raman crystals…
For example, selected eye-safe lasers could cause personal injury on the cornea or the lens, notably When the exposure is prolonged or even the laser energy is large.
Figure 2(b) shows the fundamental laser beam radius check here on both equally the Nd:YVO4 plus the diamond underneath unique thermal lens focal lengths. In the case of a thermal lens which has a focal size as small as a hundred and seventy mm, the cavity is able to maintain a nicely-matched connection among the pump and the fundamental laser.
The one.5 µm wavelength region is especially fascinating as it coincides with the least water absorption in Organic tissue. This attribute will make Yb:Er:glass a great choice for biomedical programs, the place it’s important to lower possible tissue problems.
These crystals enable scientists to acquire precise knowledge in regards to the drinking water vapor profile in the ambiance, and that is critical for climate prediction and local climate reports.
We existing an conclusion-pumped ongoing-wave intra-cavity yellow Raman laser at 590 nm that has a 60 mm extended pure crystal SrWO4 and an intra-cavity LiB3O5 frequency doubling crystal. The highest output power…
Also, this excellent power dealing with skill also contributes on the long operational lifetime and reliability of Tm:YAG crystals.
When we discuss of Yb:Er:glass, we check with a laser crystal that generally operates in an eye fixed-safe spectral region of all over 1.5 µm. This wavelength region doesn’t just appear appealing on the area; it carries major implications for your big selection of applications.
