CleanLaze® Spectrum Stabilized Fiber Coupled Lasers

cleanlazusb
    U.S. patent number 7,245,369

   ce     ul     rohs     iso 

The CleanLaze® laser series is capable of maintaining a linewidth of less than 0.03nm (15GHz) in single transverse mode operation at 785nm. The core part of this laser is a high-power broad-stripe laser diode with its output spectrum narrowed and stabilized using a novel cavity technology. Conventional external cavity lasers are both delicate and high in maintenance cost due to the inclusion of external reflective dispersive elements resulting in a long cavity length. While in the CleanLaze®, the wavelength selective element is an integral part of the laser diode through a hybrid integration process, resulting in an ultra compact footprint (4mm x 4mm x 3mm) which is stable against environmental changes (temperature, vibration, humidity, etc.). The utilization of a broad-stripe laser diode guarantees a low cost module while delivering higher output power than its DFB and DBR counterparts. The wavelength selective element filters out unwanted spectral sidelobes from the broad-stripe laser diode and locks its output wavelength to the filter’s central wavelength.

Features:
• Narrow Linewidth (Less Than 0.03nm)      • Power Output from 50mW to 4W
• Lifetime greater than 10,000 Hours      • Excellent Spectral and Power Stability
• Free-space or Fiber Coupled      • USB Software Interface Available
• Rugged Environmentally Sealed Design

RMS Noise Specs

graph
The CleanLaze® can be operated in a wide temperature range (10oC - 35oC), with a stable and quiet laser output power at most wavelengths. The CleanLaze® has a proven history of RMS noise stability < 0.5%. The combination of excellent beam characteristics (such as mode quality, low divergence, and brightness), makes the CleanLaze® laser series suitable for beam focusing, as well as for long distance beam positioning.

Digital Modulation / External Trigger Specs

graph



With the TTL modulation option the laser can be digitally pulsed in on/off mode up to 100kHz in multi-mode with a modulation depth greater than 100:1. With a rise / fall time of less than one microsecond the TTL signal can be incorporated with the trigger signal of your detection system to control your measurement cycle and integration time. TTL modulation is ideal for Raman spectroscopy, fluorescence spectroscopy, and other application where the source and the detector need to be precisely triggered.

Analog Modulation Specs

graph



With analog modulation (AM) the laser output power is controlled by applying an arbitrary 0-5V input signal from a function generator. With the AM option the laser can be modulated up to 1kHz in multimode operation with a modulation depth greater than 100:1.

Applications

graphIdeal source for Raman spectroscopy as well as fluorescence spectroscopy. Our patented* CleanLaze® technology utilizes a clean, narrow bandwidth laser which makes it ideal for Raman spectroscopy since the quality of the Raman peaks are directly related to the sharpness and stability of the delivered light source.

The CleanLaze® offers a long coherence length which is ideal for high resolution metrology, microscopy and digital holography.

The narrow linewidth of the CleanLaze® can be utilized for injection seeding of high power lasers and nonlinear devices, such as optical parametric generation (OPG). The 808nm CleanLaze® model can also be used as a narrow linewidth pump source for Nd:YAG / Nd:YVO4 lasers.
