Spectrum

Figure 1 Main power end spectrum (center wavelength 1551.9nm)

The repetition frequency range of fiber pulse laser is 100kHz-3MHz. The maximum repetition frequency will decrease when the main power is low. The repetition frequency diagrams of 100kHz and 3MHz are shown in Figures 1 and 2.

Figure 2 100kHz repetition frequency

Figure 3 3kHz repetition frequency

Table 1 shows the main power of the laser at different repetition frequencies and different pulse widths at 25°C and DAC=100. From Table 1, it can be seen that the main power increases with the increase of repetition frequency or pulse width.

Table 2 shows the main power corresponding to different DACs when the laser is at 25°C, repetition frequency = 1MHz and pulse width = 3ns. The maximum main power can reach 1.217W.

The relationship between the laser main power and DAC is shown in Figure 3, and the linearity is good.

Testing and usage requirements

1. Heat dissipation requirements

This light source consumes a lot of power and must be well cooled, otherwise the light source cannot work well, affecting the stability of the equipment or causing damage.

2. Repetition frequency and output power requirements

This product needs to be used at a continuous repetition frequency with uninterrupted trigger pulses;

3. Power supply use

Please make sure that the input power is within the voltage and current range required by the product indicators, and the power must not be directly cut off when it is not turned off during use. If there is an accidental power outage, be sure to turn off the power of the product.

4. Electrostatic protection

The laser and some chips inside this pulse light source are electrostatic sensitive devices, which are prone to irreversible damage when there is high static electricity outside. The equipment needs to be well grounded and the operator should take electrostatic protection measures.

5. Optical fiber end face protection

Before use, clean the end face of the output optical fiber with a wipe paper dipped in alcohol to ensure that the output end face is clean, otherwise the output power or stability will decrease easily, and even the optical fiber end face will burn.

6. Personal safety

The pulse light source belongs to Class IV light source. When working, you cannot look directly at the output end of the optical fiber with your naked eyes, and you cannot expose your skin directly to strong light, otherwise it will cause damage.
