Description
405 nm single longitudinal mode (SLM) diode laser, purpose-built for the demanding realm of
quantum cryptography. Its exceptional coherence and minimal linewidth make it a vital tool for the
application. Its applications extend to quantum key distribution systems, quantum encryption
networks, and quantum communication protocols, all of which rely on its precision and stability to
safeguard sensitive data against potential threats. These features make it an ideal choice for
quantum key distribution and secure data transmission in quantum encryption systems, ensuring the
utmost data security in a straightforward and practical manner.
This model could also be used in compact Raman spectrometers or fluorescence microscopes. 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.

This free-space laser can be supplied with an integrated clean-up filter.
Note:
In optical systems with strong back-reflections (e.g. more than 10%), 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 for cases of COD (Catastrophic Optical Damage) of laser diode facets.
