Description
Polarization-maintaining (PM) fiber coupled SLM 405 laser is distinguished by a very good beam quality and homogeneity. Integrated power electronics and monolithic fiber attachment makes this laser imune to thermal changes in the environment and the output delivers spatially filtered TEM00 polarized radiation.

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 10-20 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 Long term power test is carried out using an optical power meter with an input bandwidth of 10 Hz. Actual measurement rate has a period of about 20 seconds to 1 minute.
4 Long term power test is carried out using an optical power meter with an input bandwidth of 10 Hz. 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 SLM lasers shall not be modulated - use external modulators instead.
7 Excluding control interface pins and an output window/fiber assembly.
8 Whichever occurs first. The laser has an integrated operational hours counter.
