Acousto-Optic Q-Switches (AOQS) – Precision Control for High-Power Laser Pulses

CASTECH’s Acousto-Optic Q-switches are advanced devices used in laser systems to achieve precise control over pulse generation. By modulating the Q-value within the laser cavity, AOQS devices can efficiently manage energy accumulation and release, resulting in powerful, high-peak laser outputs. These Q-switches are critical components in applications that require high-intensity, short-duration laser pulses.

Key Features:

• High Damage Threshold:
  With a high damage threshold, these Q-switches are designed to withstand intense laser pulses without degradation, ensuring long-term reliability in high-power applications.

• High Modulation Loss:
  The AOQS effectively increases diffraction loss in the cavity, allowing for precise control over the Q-value, resulting in optimized laser pulse generation.

• Wide Operating Wavelength Range:
  Our Q-switches cover a broad wavelength range from 310 nm to 10.6 μm, making them versatile for various laser applications across different industries.

• High Transmittance:
  With single-pass transmittance of up to 99.6%, these devices ensure minimal energy loss and maximum efficiency during laser operation.

• Fast Switching Speed:
  The fast switching capability of AOQS devices allows for precise timing control in Q-switching, enabling the generation of high-energy pulses in extremely short durations.

• Water Cooling for High RF Power Injection:
  To achieve higher diffraction efficiency, large aperture AO Q-switches require substantial RF power, necessitating a water-cooling system for efficient heat dissipation.

Applications:

• Laser Marking:
  Ideal for precision laser marking processes, ensuring high-contrast, high-quality results on a variety of materials.

• Medical Procedures:
  Used in medical lasers for applications like ophthalmic surgery, dermatology, and other treatments requiring precise laser pulses.

• Material Processing:
  Perfect for cutting, welding, and engraving in industrial material processing applications where high-intensity, short-duration laser pulses are critical.
