405 nm SLM Laser (HP VBG Diode; PM Fiber)
Select Fiber Termination:
Full production Product specifications are stable. Delivery time is predictable.
State-of-the-art 405 nm polarization-maintaining (PM) fiber-coupled diode laser, meticulously engineered to meet the standards of quantum cryptography. This laser operates at a single frequency, emitting a 405 nm wavelength beam with unrivaled precision and coherence. What sets it apart is its integrated polarization-maintaining fiber, ensuring the preservation of polarized light throughout your applications. This capability is crucial for quantum key distribution and secure data transmission, setting new benchmarks in data security.
PM fiber-coupled SLM 405 laser is distinguished by a very good beam quality and homogeneity. Integrated power electronics and monolithic fiber attachment make this laser immune to thermal changes in the environment and the output delivers spatially filtered TEM00 polarized radiation.
By default, this type of laser is built with FC/APC connector, but other fiber terminations are available upon request. Details about non-standard connector and the fiber used with it should be discussed with the Integrated Optics sales team.
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.
Fiber Termination - FC/APC (AT): 8° polishing angle minimizes back reflections from fiber tip. This is necessary especially for SLM lasers.
