300 mW Micro RGB Laser Module

About 300 mW Micro RGB Laser Module

This is compact and lightweight free-space laser module with multiple wavelengths.

Wavelengths

The laser module outputs three wavelengths:

• Channel R: 638nm (+5/-3nm)
• Channel G: 520nm (+10/-5nm)
• Channel B: 450nm (+/- 10nm)

Wavelength tolerance can be changed for special order.

Laser Beam

The laser module outputs three laser beams which are overlapping. The dimensions of the laser beams are:

• Channel R: 1.6 x 1.0 mm @ 1/e2
• Channel G: 2.8 x 0.8 mm @ 1/e2
• Channel B: 3.0 x 1.2 mm @ 1/e2

All of the beams are collimated. The divergence in the fast axis < 1.0mRad, the divergence is the slow axis <1.3mRad.

Polarization

The polarization state of each laser beam is the same, and it is TE-polarization.

Optical Power

Typical total optical power is 300 mW and minimal optical power is 280 mW.

Dimensions

The dimensions of the module are 44 x 39 x 27 mm. It is possible to mount the module on the base plate using four M3 screws. 

Laser Diode Driver

The module is controlled by a three-channel driver (LPLDD-1A-16V-3CH). Each channel is independently controlled by Analog or TTL input. The modulations up to 100 kHz is achievable. Modulation inputs can be used as a TTL inputs with its logic levels of 0 V and 5 V or as an analog input.

Caution! Class 3B Laser !

1. Only person with specialized training and appropriate laser safety knowledge can use and maintain the laser module. The laser module operator must be aware of laser radiation hazard.
2. Laser radiation is dangerous even when scattered or reflected off a surface.
3. Always use proper laser filter protection 
4. Never point lasers at people or animals.
5. Do not stare at the beam, devastating and permanent eye damage can occur as a result of direct, diffuse or indirect beam viewing.
