A new type of solid-state laser, which combines light, machine and electricity, is a diode-pumped passive Q-switched YAG laser that was successfully developed and passed the expert appraisal at Changchun University of Science and Technology.

Experts believe that the research of laser diode passive Q-switched YAG laser has reached the domestic leading level, and solved the following key technologies in optical coupling, Q-switching and other technologies: self-focusing lens and hollow circular table laser fiber coupler (obtained by national invention patent) Instead of the traditional complex optical system combination, the effective space matching between the pumping light and the oscillating laser is realized, and stable single-mode operation is obtained. By controlling the electric pump injection pulse width, the initial transmission of the passive Q-switched Cr4+:YAG crystal is determined. The rate and the output mirror reflectance enable passive Q-switchable single-pulse laser output.

At present, the research group is conducting further research on improving the repetition frequency of laser work, and strives to enter the market as soon as possible.

Excavator Grapple

CATSU 5-tooth grapple could refer to a type of attachment for heavy equipment such as excavators or skid steers. It is designed to grip and hold materials such as logs, rocks, and debris with its five sharp teeth.

CATSU 5-tooth grapple can be operated hydraulically and is commonly used in forestry, construction, and demolition industries.

CATSU excavator grapple is an attachment that is mounted on the arm of an excavator, which is used to grab and hold onto objects.

CATSU excavator grapple is designed to be used for a wide range of applications, including demolition, construction, forestry, and landscaping.

CATSU excavator grapple is made up of a set of jaws that can be opened and closed using hydraulic power, allowing it to grab and hold onto objects of various sizes and shapes.

CATSU excavator grapples come in different sizes and configurations to suit different types of jobs and excavators of different sizes.
