Discharge circuits from OEM Tech


For R&D engineers developing flashlamp-pumped laser systems, the performance and reliability of the discharge circuit are of the utmost importance. This component directly influences pulse stability, energy delivery, and the operational lifespan of the flashlamp. At OEM Tech, we design and manufacture a range of discharge circuits specifically for these applications, focusing on precise control, efficient operation, and simplified integration.


OEM-Tech's Discharge Circuit Capabilities

Our discharge circuits are engineered to provide essential functionality for diverse laser pumping requirements:

  • Integrated Functions: Modules from our NBU series include integrated simmer and trigger circuits. This reduces the need for external components, simplifying system design and accelerating integration into host laser systems.
  • Compact Form Factor: Designed to minimize footprint, our units reducing the overall system size.
  • Control Interfaces: Our modules support control via TTL, but other (RS-232 or RS-485) interfaces are possible. This provides flexibility for integration with various control systems and allows for precise remote parameter adjustment.
  • Robust Design: Key features like temperature protection are integrated to ensure reliable operation under continuous use and demanding conditions, maintaining system stability.

Product Series Overview

Our discharge circuit portfolio includes dedicated solutions for various energy and repetition rate requirements:

NBU Series: Pulsed Discharge Units for Flashlamp Pumping

The NBU series is engineered specifically for flashlamp pumping, providing high-energy pulsed power with consistent performance.



  • The discharge circuit NBU-1012: IGBT-based. Offers quasi-rectangular pulses with the maximum pulse voltage up to 1000 V and pulse current up to 1000 A for pulses less than 1 ms (depends on flashlamp impedance K0). A repetition rate is up to 100 Hz.
  • The discharge circuit NBU-0808: IGBT-based. Offers quasi-rectangular pulses with the maximum pulse voltage up to 800 V and pulse current up to 1000 A for pulses less than 1 ms. A repetition rate is up to 100 Hz.
  • The discharge circuit NBU-1508: Thyristor-based. Provides bell-shaped output pulses from complete discharge of 100 uF capacitor bank. Typical applications are Q-switched Nd:YAG lasers or similar. Offers the maximum pulse voltage up to 1500 V and pulse current up to 1000 A for pulses less than 1 ms.

These units are particularly suitable for medical, cosmetic, and scientific research applications where consistent, high-repetition pulsed energy is required. All our NBU discharge circuits offer Flexible Triggering: include capabilities both for serial and external triggering.

 

NBD Series: Dual Channel Discharge Circuit with PWM

The NBD-0505-PWM offers a versatile solution for systems requiring both IPL and/or solid-state laser system flashlamp pumping capabilities. The unique feature is advanced current control (PWM), which makes true rectangular pulses possible.

  • Dual-Channel Operation: This unit can provide rectangular pulses up to 500 V / 500 A in PWM mode for and deliver quasi-rectangular pulses up to 800 V / 800 A in free-discharge mode (not simultaneously).

Integration and Application

Our discharge circuits are designed for direct integration into laser systems. By providing precise control, safety features, and flexible interfaces, these units help engineers shorten development cycles and ensure reliable, high-performance operation of their flashlamp-pumped lasers.

Using the QBX-08 Pockels cell driver for double-pulsed LIBS

Image
  Double-pulse Q-switched Nd:YAG laser with one  resonator design using the OEM Tech's QBX-08 special Pockels cell driver for LIBS. Double-pulse Nd:YAG lasers are used for LIBS and PIV applications. Widely known design with two independent lasers generating two pulses (collinear or orthogonal) requires two two laser cavities, so basically all optical and electronics components are doubled; moreover lot of optics is needed to combine both beams. The use of adjustable waveform Pockels cell driver  QBX-08  lets generate two laser pulses with controllable time delay (in order of 5 us between pulses) by one laser (see pic.1). The schema is simple, and it was tested in practice for LIBS experiments, showing significant improvement of line intensities with low background. The first pulse in this scheme carries about 10-20% energy of the second pulse. EmICCD (electronically intensified camera) which provides both high-amplification and optical gating is recommended to captur...
