Description

This 830 nm laser features a tunable single-longitudinal-mode (SLM) and operates in multiple transversal modes. It used mainly in industrial applications of Raman spectroscopy, where a high-power single-frequency operation is needed without the necessity of sharp focusing.

The transversal modes are distributed in one row, thus the fast axis can be focussed with M2 ~1.3, while the slow axis has multiple modes and its focusability is poor - theoretically, it can be focussed to a width of ~50 µm.

This laser is a Volume Bragg Grating (VBG) stabilized diode laser, which is distinguished by high electrical efficiency and exceptional wavelength stability.

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

1 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.

2 Without a clean-up filter installed.

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 For lasers without integrated optical isolators.

7 Break-out-boxes AM-C8 and AM-C3 can be used for conversion of UART communication to either USB or RS232.

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
