405 nm SLM Laser
Item Code: 0405L-24A-NI-AT-NFDescription
Fiber Termination - FC/APC (AT): 8° polishing angle minimizes back reflections from fiber tip. This is necessary especially for SLM lasers.

1 Measured with a scanning Fabry-Perot interferometer having 7.5 MHz resolution, with scanning frequency of about 10 Hz. Interferometer testing is not provided for each laser being manufactured, the standard test is OSA measurement with 20-30 pm resolution instead.
2 The output power of SLM lasers shall not be tuned and SLM performance is not guaranteed at power ratings other than factory preset. However, the power setting capability is not disabled. External attenuators are recommended instead.
3 The long term power test is carried out at constant laser body temperature (+/-0.1 °C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.
4 The long term power test is carried out at constant laser body temperature (+/-0.1 °C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.
5 Noise level is measured with a fast photodiode connected to an oscilloscope. The overall system bandwidth is from 2 kHz to 20 MHz.
6 Break-out-boxes AM-C8 and AM-C3 can be used for conversion of UART communication to either USB or RS232.
7 APC - Automatic Power Control.
8 SLM lasers shall not be modulated - use external modulators instead.
9 Excluding control interface pins and an output window/fiber assembly.
10 Whichever occurs first. The laser has an integrated operational hours counter.
11 Converted from bandwidth value.

Raman Spectroscopy
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
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.
