High-Energy Femtosecond Fiber Laser System
BLUECUT and BLUECUT-515 Applications
OEM Seed Laser Features
The BLUECUT is an industrial-grade, microjoule femtosecond fiber laser system. Based on all-fiber integrated technology, this is an inherently robust and stable system which comes in a sealed package designed for OEM integration. The system is maintenance free and easily field serviceable, ensuring maximum up-time demanded by both industrial and scientific applications. The high repetition rates available from the laser combined with its high average power and beam quality allow for high throughput and increased efficiency. The BLUECUT laser operates at 1030 nm; a 515 nm version (item # BLUECUT-515) is also available.
The OEM seed laser (item # BLUECUT-OEM-SEED) is a high repetition rate, ultrashort pulsed laser in a compact turnkey design based on Menlo Systems' figure 9® mode-locking technology. It is designed as a seed source for ultrafast chirped pulsed laser amplifiers. Center wavelengths from 1025 nm to 1070 nm are available, allowing for seeding of active solid state and fiber laser materials. It is suitable for generating high-power pulses shorter than 300 fs. The laser covers a wide range of repetition rates with constant pulse energy. The BLUECUT-OEM-SEED is designed for industrial application with full remote control over its RS232 or USB interface. The compact rack mount housing allows for easy integration into high-power laser systems.
Pulsed Laser Emission: Power and Energy Calculations
Determining whether emission from a pulsed laser is compatible with a device or application can require referencing parameters that are not supplied by the laser's manufacturer. When this is the case, the necessary parameters can typically be calculated from the available information. Calculating peak pulse power, average power, pulse energy, and related parameters can be necessary to achieve desired outcomes including:
Pulsed laser radiation parameters are illustrated in Figure 1 and described in the table. For quick reference, a list of equations are provided below. The document available for download provides this information, as well as an introduction to pulsed laser emission, an overview of relationships among the different parameters, and guidance for applying the calculations.

Figure 1: Parameters used to describe pulsed laser emission are indicated in the plot (above) and described in the table (below). Pulse energy (E) is the shaded area under the pulse curve. Pulse energy is, equivalently, the area of the diagonally hashed region.
Is it safe to use a detector with a specified maximum peak optical input power of 75 mW to measure the following pulsed laser emission?
The energy per pulse:
seems low, but the peak pulse power is:
It is not safe to use the detector to measure this pulsed laser emission, since the peak power of the pulses is >5 orders of magnitude higher than the detector's maximum peak optical input power.
