Blue Laser

Product catalog summary

Specifications:
The PL 450B is a blue laser diode with a typical emission wavelength of 450nm. It is designed for both continuous wave (cw) and pulsed operation, featuring a single transverse mode and high modulation bandwidth. The diode is housed in a miniaturized TO38 ICut package and is electrically isolated from the package.

Applications:
This laser diode is suitable for laser projection, instrumentation, biomedical applications, holography, and metrology.

Safety and Standards:
The diode emits highly concentrated visible light, which can be hazardous to the human eye. Products incorporating this diode must comply with IEC 60825-1 safety standards.

Maximum Ratings:
- Optical Output Power: Max 100 mW
- Operating Current: Max 165 mA
- Operating Temperature: 10 to 70 °C
- Storage Temperature: -40 to 85 °C
- Reverse Voltage: Max 2 V
- Soldering Temperature: Max 260 °C for 10 seconds

Laser Characteristics (at Tcase = 25 °C):
- Emission Wavelength: 440 to 460 nm
- Spectral Width (FWHM): 2 nm
- Threshold Current: 30 to 60 mA
- Operating Current: 100 to 145 mA
- Operating Voltage: 5.8 to 7.0 V
- Beam Divergence (FWHM): 4x18 to 11x25 degrees
- Polarization: 20:1
- Modulation Frequency: >100 MHz

Operational Notes:
- The laser diode is classified as Class 3B according to IEC 60825-1.
- It requires a low-noise power supply and is sensitive to electrostatic discharge (ESD).
- Proper heat management is crucial, with heat dissipated through the diode's base plate.

Package and Pin Configuration:
The diode is packaged in a TO38 ICut form with specific pin connections for anode, cathode, and case.

Compliance and Handling:
The product is EU RoHS compliant. OSRAM provides guidelines for recycling and handling of packing materials. Components used in life-support systems require explicit authorization from OSRAM.

Wichtige Hinweise zum Betrieb der Die Laserdiode wurde in Klasse 3B gemàB der Laserdiode tatsàchlich emittierte Strahlung hángt in erster Linie von den Betriebsbedingungen ab. OSRAMs Laserdioden sind mit dem Ziel höchster Leistung und Zuverlàssigkeit gefertigt. Der Betrieb der Laserdiode oberhalb der im Datenblatt angegebenen Maximalwerte kann jedoch die Leistung und die Zuverlàssigkeit erheblich beeintràchtigen. Daher solite die Laserdiode auch mit einer möglichst rauscharmen Stromversorgung betrieben werden. Die Laserdiode ist sehr empfindlich gegenüber Entsprechende VorsichtsmaBnahmen sind...
