Laser pumping is the foundation of many advanced optical systems. Whether you’re working with solid-state, alkali, or fiber lasers, the efficiency, stability, and longevity of your system heavily rely on the quality of its pump source. At Akela Laser, we specialize in high-power diode lasers designed for optimal performance in demanding laser pumping applications. Our solutions include both fiber-coupled and free-space diode modules, tailored to meet the stringent requirements of modern photonics systems.

The Role of Diode Lasers in Optical Pumping

Diode lasers have become the standard for laser pumping due to their high electrical-to-optical conversion efficiency, customizable output, and compact form factors. As core components in many commercial and scientific systems, these lasers enable high-output performance in a wide range of laser types.

Pumping Solid-State Lasers

Solid-state lasers, including Nd:YAG and other crystal-based systems, require a precise pump source for stable output. Akela’s diode modules deliver the required wavelengths with tight linewidth control, enabling excellent absorption and energy conversion in the gain medium.
Our laser diode modules can be wavelength-locked for specific applications, ensuring the exact emission needed for maximum efficiency. With high brightness and adjustable power levels, these modules are a dependable choice for laboratories and OEM manufacturers alike.

Pumping Fiber Lasers

Fiber lasers rely on diode pumping for their core operation. Our high-power laser diode modules offer unmatched brightness and beam quality, supporting direct coupling into fiber systems. These modules are available in fiber-coupled packages designed to integrate easily into OEM platforms and laboratory systems.

Akela Laser offers multiple coupling options, including standard SMA connectors and customized fiber termination for specialized use cases.

Pumping Alkali Lasers

Alkali vapor lasers require narrow linewidths and precise wavelength matching. Our advanced modules can incorporate emission line narrowing and temperature tuning features to meet the exacting standards of alkali laser applications. These modules are ideal for both experimental and deployed systems that depend on reliable, long-lifetime performance.

Types of Laser Pump Modules We Offer

At Akela Laser, our goal is to offer flexible and modular pumping solutions that can be adapted to any optical platform. All products are built to meet high thermal, electrical, and optical performance standards.

Free-Space Laser Diode Modules

Free-space modules provide excellent beam quality and flexibility for systems that do not require fiber coupling. These modules are ideal for research applications and system integration where precision beam shaping is essential. We offer custom housing and beam delivery configurations to match the user’s optical setup.

Fiber-Coupled Laser Diode Modules

Fiber-coupled laser diodes are the preferred choice for compact integration and remote delivery. These modules offer robust thermal management and high coupling efficiency, making them perfect for environments that require mechanical stability or remote pump delivery.

Akela Laser’s two-wavelength laser modules and custom dual-wavelength laser modules provide greater flexibility and control, ideal for hybrid laser systems and complex R&D setups.

Multi-Wavelength and Narrow Linewidth Options

In addition to traditional single-wavelength modules, Akela offers multi-wavelength medical lasers and three-wavelength diode laser module designs for systems that require spectral versatility. Our laser diodes can be customized with external feedback components to support wavelength locking, emission narrowing, and precision tuning.
These options are particularly valuable for:

• High-resolution spectroscopy
• Medical and diagnostic lasers
• Quantum optics experiments
• Custom laser sources for industry-specific applications
