561nmlaser

High-performance 405 nm single longitudinal mode (SLM) laser, designed with precision for applications in Raman scattering and fluorescence studies. This laser provides a stable and narrow linewidth output at a 405 nm wavelength. Its meticulously engineered single-mode characteristics make it an ideal tool for these precise applications. Laser offers a powerful and reliable solution for researchers and scientists. Its lower power output allows for gentle and controlled excitation of molecular vibrations and fluorescence, without causing sample damage. Whether you're delving into material analysis or probing the intricate world of biomolecules, this laser empowers you with the accuracy and versatility required for groundbreaking discoveries in these fields.This model of SLM 405 nm laser is widely used in compact Raman spectrometers. Small footprint and +5 VDC operating voltage is exactly what's needed for handheld portable devices. Integrated precision driver electronics ensure low-noise and stable operation throughout the wide temperature range. 405 nm radiation features high-energy photons, therefore much lower power is enough for efficient excitation of fluorescence or Raman scattering.This free-space laser can be supplied with an integrated clean-up filter. Note:Back-reflections to the laser can cause spectral widening or even a COD (Catastrophic Optical Damage) of laser diode facet. In optical systems with significant back-reflections (e.g. more than 0.5%), the laser must be protected by using an optical isolator with at least 20 dB isolation. Typical applications include interferometry, confocal microscopy (especially working with reflective samples), etc. Failure to comply with these requirements will render the warranty void.

Raman Spectroscopy is a powerful analytical technique that explores molecular vibrations by measuring inelastic scattering of monochromatic light. It provides valuable insights into molecular structure, composition, and chemical bonding, making it widely used in material science, chemistry, and biology. The unique spectral fingerprints obtained through Raman spectroscopy enable non-destructive and precise identification of substances, making it a versatile tool for research and quality control applications.

Quantum cryptography is a way of securing information using the principles of quantum physics. One method of quantum cryptography is quantum key distribution (QKD), which allows two parties to share a secret key that can encrypt and decrypt messages. QKD uses entangled photons, which are pairs of light particles that have a quantum connection and share the same properties. By measuring the polarization of one photon, the other photon will have the same polarization, even if they are far apart. This way, the two parties can generate a random sequence of bits that form the key. However, to create and send entangled photons from space, they need small lasers that can fit into smallsats.

7&nbspThe beam of this laser usually contains small artifacts, which make the M2y measurement worse. The beam quality improvement on Y-axis (vertical) is possible by sacrificing some output power (up to 30% loss of power). However, in applications where SM fiber coupling is needed, even at M2y=2.0 we guarantee that 50% of radiation will be coupled into the fiber.
