The passive Q-switch functions as a saturable absorber. When it is excited by laser light, it accumulates energy and reaches a state of saturation, causing its transmission to increase rapidly and reducing the resonator loss, ultimately leading to the generation of laser pulses. The pulse energy and duration are typically fixed, with an increase in pumping power resulting only in an increase in the repetition rate of the pulses.
OST Photonics supplies passive Q-switch crystals including Cr4+:YAG and Co2+:MgAl2O4. Cr4+:YAG is an excellent saturable absorption material for Nd and Yb doped lasers(especially for Yb: YAG laser, Nd: YAG laser or Nd: YVO4 lasers). Co2+:MgAl2O4 (Co2+:Spinel) crystals are a novel material for passive Q-switching in lasers that emit within the range of 1.2 to 1.6 µm, particularly suitable for eye-safe 1.54 µm Er: glass laser systems, while also working at wavelengths of 1.44 µm and 1.34 µm. If you want to know more about Q-Switch crystals, contact OST Photonics now, we are a professional passive Q-switch crystals supplier.
Co2+:MgAl2O4 crystals are an effective material for passive Q-switched solid-state lasers operating in the near-infrared region. The pulsed laser generated by its passive Q-switching action has characteristics such as minimal damage to the human eye, strong penetration, low transmission loss, and high photoelectric resistance. It can be widely used in space optical communication, rapid ranging on the battlefield, and laser radar for unmanned equipment.
Passive q-switch crystal is a kind of material with special properties. It plays an important role in the field of optics and is widely used in the fields of lasers, optical communication equipment and medical instruments. This kind of crystal has the advantages of high efficiency, good stability and long life.
First of all, passive q-switch crystals have the characteristics of high efficiency. It can quickly and precisely adjust the laser output frequency so that the laser can work more efficiently. This is critical for many applications that require high precision control, such as radar systems and scientific research centers.
Secondly, passive q-switch crystals also show good stability. Regardless of temperature changes or other environmental conditions, it can maintain a relatively constant working state and is not easily affected by external interference. This makes passive q-switch crystals an indispensable component in devices with high reliability requirements.
In addition, passive q-switch crystals also have a long service life. Due to its reasonable structural design and excellent material quality, it can maintain stable operation for a long time under normal use. This reduces the cost of maintenance and replacement parts and improves the reliability and economy of the entire system.
In short, passive q-switch crystals, as an important material, play a huge role in various fields. Its characteristics of high efficiency, good stability, and long life make it one of the essential elements in many technical devices and promote the technological progress and development of related industries.
Q-switching, also known as giant pulse generator, is a pulsed laser generation technology.
Cr:YAG crystals have superior chemical stability, ultraviolet radiation resistance, good thermal conductivity, and high damage threshold.
