Review THORLABS 405 Nm 40 Mw 5.6mm Pin Code Laser Diode

The Thorlabs DL5146-101S is a powerful and versatile 405 nm, 40 mW 5.6 mm diameter laser diode. This diode is an excellent choice for various applications in fields such as biology, spectroscopy, and materials processing.

The DL5146-101S emits a coherent and monochromatic beam at a wavelength of 405 nm, which is located within the violet region of the visible light spectrum. The high power output of 40 mW is delivered through a 5.6 mm diameter, 0.37 NA, AR-coated fiber pigtail. This fiber pigtail facilitates easy integration with optical systems by reducing the need for additional optics and alignment efforts.

Thorlabs' DL5146-101S diode is designed for reliable and stable operation. It features a constant-current forward voltage of 7.2 V and a maximum reverse voltage of 10 V. A built-in thermal protection circuit ensures that the diode does not overheat during operation, while an automatic power control function maintains a constant output power, even under varying temperature conditions.

The DL5146-101S diode is housed in a robust, compact package that measures 24.2 mm 12.1 mm 6.5 mm. The diode's compact size and fiber coupling simplifies system design and reduces overall system cost. The diode also comes with a protective window that shields the emitting surface from contamination and damage.

In summary, the Thorlabs DL5146-101S is a high-performance, 405 nm, 40 mW laser diode that offers a compact, fiber-coupled design and reliable operation. It is suitable for a wide range of applications in fields such as biology, spectroscopy, and materials processing, where a powerful, monochromatic violet light source is required.

The Thorlabs DL5146-101S 405 nm 40 mW 5.6 mm laser diode is a commonly used laser diode in various applications, especially in the field of scientific research and industrial processing. Let's discuss some pros and cons of buying this laser diode:

1. Power Output: This laser diode provides a maximum output power of 40 mW, which is sufficient for many applications that require a high power 405 nm laser source.

2. Monochromatic: The laser diode emits a single wavelength of 405 nm, making it monochromatic, which is essential for many applications that require high spectral purity.

3. Compact Size: The laser diode has a small footprint and can be easily integrated into various systems, making it a popular choice for those who require a compact and powerful laser source.

4. Reliability: Thorlabs is a well-known and reputable manufacturer, and the DL5146-101S laser diode is known for its reliability and durability, making it a good investment for long-term use.

1. Cooling Requirement: The laser diode requires external cooling to maintain stable operation and prevent overheating. This can add to the cost and complexity of the system.

2. Limited Modulation Bandwidth: The laser diode has a limited modulation bandwidth, which may not be suitable for some applications that require fast modulation speeds.

3. High Power Density: The laser diode has a high power density, which can be a safety concern and requires proper handling and safety measures to prevent injury or damage.

The Thorlabs DL5146-101S 405 nm 40 mW 5.6 mm laser diode is a powerful and reliable laser source that is suitable for a wide range of applications. Its monochromatic nature and compact size make it a popular choice for many researchers and industrial users. However, its requirement for external cooling and limited modulation bandwidth are potential drawbacks that need to be considered.

If you require a high power, monochromatic 405 nm laser source for your application and are willing to invest in external cooling, then the Thorlabs DL5146-101S laser diode is an excellent choice. However, if you have applications that require fast modulation speeds or do not need the high power density, you may want to consider alternative laser sources or modifications to the system design.
