Description

Single-longitudinal mode (SLM) 633 nm laser is a replacement for HeNe, where high coherence length and exact center wavelength is needed. This configuration provides a perfect diffraction-limited beam from an SM fiber. Small footprint and +5VDC (USB typical) operating voltage is exactly what's needed for handheld portable devices. Integrated precision driver electronics ensure low-noise and very stable operation throughout wide temperature range. 633 nm red radiation features average photon energy. VBG technology delivers a low-cost solution to sophisticated Raman spectroscopy and various metrology needs.

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.

1 Measured using HighFinesse LineWidth Analyzer LWA-10k having 10 kHz resolution. Linewidth Analyzer 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 SLM lasers shall not be modulated - use external modulators instead.

8 Excluding control interface pins and an output window/fiber assembly.

9 Whichever occurs first. The laser has an integrated operational hours counter.

10 Converted from bandwidth value.
