Description
Product Overview
The JDSU M112M-4919-03 is an IPW1064nm100K laser head associated with the JDS Uniphase M112M laser platform. Available equipment records identify this model as a 1064 nm laser head, with the part number also listed as IPW1064nm100K.
The unit is intended for use with the corresponding JDSU laser system and power/control equipment rather than as a general-purpose standalone laser source. Matching the complete model number, connector arrangement, and system configuration is recommended before installation.
This model is commonly encountered as a spare or replacement component in semiconductor and industrial laser equipment inventories.

Typical Applications
The M112M-4919-03 may be encountered in equipment using pulsed 1064 nm laser sources, including industrial laser processing, semiconductor manufacturing equipment, optical processing systems, and laboratory or research equipment.
For semiconductor-tool applications, the exact machine configuration should be checked before ordering because laser heads with similar M112M designations may not share the same optical or electrical configuration.
Installation & Configuration
Before installation, compare the replacement unit with the existing laser head:
- Confirm the complete part number: M112M-4919-03.
- Verify the IPW1064nm100K identification where applicable.
- Check all optical, electrical, and control connections.
- Inspect connectors and cable assemblies for contamination or physical damage.
- Confirm compatibility with the existing M112M power/control equipment.
- Install the head according to the equipment manufacturer’s service procedure.
- Perform a controlled power-up and verify system status before enabling laser emission.
Important: A laser head should not be connected to an incompatible power supply or controller simply because the mechanical form is similar.
Inspection & Testing
For a used or surplus laser head, recommended inspection includes:
- Model and serial-number verification
- Housing and connector inspection
- Optical interface inspection
- Cable and connector continuity checks where applicable
- Power-up test using the correct JDSU system
- Laser emission/output verification using suitable calibrated equipment
- Operating stability check
- Inspection for abnormal heating, noise, or fault indications
Because laser output is safety-critical, functional testing should be performed by qualified personnel using appropriate laser safety controls.
Maintenance Notes
Keep the optical interfaces protected from dust and contamination. Avoid touching exposed optical surfaces. Store the laser head in suitable protective packaging when it is not installed.
Do not open or modify the laser head unless the equipment manufacturer provides a specific service procedure. Internal optical alignment can be sensitive to mechanical shock and contamination.
Frequently Asked Questions
Q: What is the wavelength of the M112M-4919-03?
A: Available equipment references identify the IPW1064nm100K / M112M-4919-03 configuration as a 1064 nm laser head.
Q: Is M112M-4919-03 the same as IPW1064nm100K?
A: Available listings associate M112M-4919-03 with the IPW1064nm100K designation.
Q: Can this laser head be used with any M112M power supply?
A: Compatibility should not be assumed. Confirm the complete part number and the required controller/power-supply configuration before installation.
Q: Is this a complete laser system?
A: No. The M112M-4919-03 is identified as a laser head/module, not a complete standalone laser system. Related M112M equipment may include separate power-supply and control components.
Q: What should I provide when requesting a replacement?
A: The complete model number, part number, serial number, photographs of the identification label, and the equipment model in which the laser head is installed are useful for compatibility verification.
Identification & Ordering Notes
Please verify the following before purchase:
- JDSU / JDS Uniphase
- M112M-4919-03
- IPW1064nm100K
- 1064 nm configuration
- Connector and cable configuration
- Physical condition and test status
The exact optical output and operating condition can vary with the individual unit. For a used or surplus replacement, matching the original part number is more reliable than selecting by wavelength alone.
