Description
Single-Mode (SM) fiber-coupled SLM or single-frequency 405 laser is distinguished by a very good beam quality and homogeneity. Highly stable mechanical design and precision control electronics render this laser as unmatched value for holography and other applications requiring high coherence length and superior beam quality.
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.
Fiber Termination - FC/APC (AT):
8° polishing angle minimizes back reflections from fiber tip. This is necessary especially for SLM lasers.
