Overview: TLS-Blue Fixed-Bandwidth Tunable Picosecond Laser

The Spectrolight TLS-Blue is a wavelength-selectable picosecond laser system for applications that require tunable center wavelength while using a consistent spectral bandwidth. It combines a broadband SL-Pico supercontinuum source with Spectrolight wavelength-selection technology in a single integrated system.

Depending on configuration, users can select tunable VIS, IR, SWIR, or custom wavelength ranges within the broader 410-1700 nm TLS platform. TLS-Blue uses a fixed 10 or 20 nm FWHM bandwidth, while TLS-Red adds adjustable bandwidth for applications that need control of both wavelength and spectral width.

TLS-Blue is a useful starting point when an imaging, inspection, spectroscopy, detector-characterization, or optical measurement setup needs wavelength-selectable illumination but does not require bandwidth to change during operation.

RPMC can help determine the appropriate source architecture, wavelength range, fixed bandwidth, output requirements, pulse width, and repetition rate for the application.

Start Here When You Need Wavelength Tuning With a Fixed Bandwidth

TLS-Blue is the likely starting point when:

You need to tune the selected center wavelength across your required spectral range.
A fixed 10 or 20 nm FWHM bandwidth works for the measurement or illumination setup.
You need wavelength-selectable illumination for imaging, inspection, spectroscopy, detector, or optical-system characterization.
Your test method does not require changing spectral bandwidth between measurements.
You need one wavelength-selectable source rather than aligning multiple independent laser sources.

If your measurement also requires control of spectral bandwidth, start with TLS-Red instead.

If you need the full broadband supercontinuum spectrum rather than wavelength-selected output, start with SL-Pico.

TLS-Blue vs. TLS-Red: Which Tunable Laser Should You Start With?

Selection Factor	TLS-Blue	TLS-Red
Center wavelength	Tunable	Tunable
Spectral bandwidth	Fixed	Adjustable
FWHM	10 or 20 nm	Approximately 2-15 nm depending on wavelength/configuration
Bandwidth adjustment	Selected fixed bandwidth	1 nm increments
VIS / IR / SWIR / Custom	Yes	Yes
Start here when…	Wavelength tuning is needed but fixed bandwidth is sufficient.	The measurement requires control of wavelength and bandwidth.

How to Configure a TLS-Blue System

Use these steps to narrow the TLS-Blue configuration before selecting the final model. The right starting point depends on the required source architecture, fixed spectral bandwidth, wavelength region, timing needs, and application setup.

1	Select the picosecond supercontinuum source Start with the required: Output level Pulse width Fixed or variable repetition rate Timing or synchronization requirements Spectrolight offers multiple SL-Pico-based source architectures and power classes.

Choose the fixed spectral bandwidth

TLS-Blue configurations use either 10 nm or 20 nm FWHM fixed bandwidth.

Select the bandwidth that matches the requirements of your measurement, imaging, or illumination setup. If the application requires the bandwidth itself to change, TLS-Red is the better starting point.

3	Choose the wavelength region Standard and custom configurations can cover portions of: VIS IR SWIR Custom-selected ranges within the overall 410-1700 nm TLS platform range.

Not sure which fixed bandwidth or wavelength range fits your setup?

Send RPMC the spectral range, required bandwidth, power, pulse width, repetition rate, detector/system information, and application.

We’ll help down-select the configuration.

Applications for TLS-Blue Fixed-Bandwidth Tunable Lasers

TLS-Blue fixed-bandwidth tunable lasers can support applications that require wavelength-selectable picosecond illumination while using a consistent 10 or 20 nm spectral bandwidth. Common use cases include spectral imaging, inspection, spectroscopy, detector testing, and optical-system characterization.

Hyperspectral and Multispectral Imaging

Wavelength-selectable illumination can support hyperspectral camera development, spectral imaging, image-system calibration, and wavelength-dependent illumination studies when a fixed spectral bandwidth is appropriate for the measurement.

Semiconductor, Wafer and Display Inspection

Spectrolight specifically demonstrates the TLS platform for silicon wafer inspection. Tunable illumination can also support optical inspection, camera testing, component QC, and wavelength-dependent transmission or reflection measurements.

Spectroscopy and Material Characterization

TLS-Blue can support spectroscopy and material-characterization experiments that need controllable center wavelength with a consistent passband, as well as filter, component, transmission, reflection, and spectral-response measurements.

Detector, Camera and Optical-System Characterization

Wavelength-selectable output can support spectral responsivity measurements, image-sensor characterization, camera development, filter testing, and calibration-system development.

What Does RPMC Need to Help Configure TLS-Blue?

Send as many of these as you know:

Required center wavelength or wavelength tuning range
Required fixed FWHM bandwidth: 10 or 20 nm
Desired optical power at the selected wavelength
Pulse-width requirements
Fixed or variable repetition-rate requirements
Triggering or synchronization requirements
Detector, camera, spectrometer, microscope, or optical-system details
Application and measurement objective
Lab, OEM, production, or other integration environment
Timeline and any special configuration constraints

You don’t need the final model number before contacting us.

RPMC can help translate your measurement requirements into a Spectrolight TLS configuration.

TLS-Blue FAQs

Below are common questions about Spectrolight TLS-Blue tunable laser configurations, wavelength coverage, fixed bandwidth options, and selection considerations.

What is the Spectrolight TLS-Blue?

TLS-Blue is a picosecond tunable laser system that combines a broadband supercontinuum source with wavelength-selection technology. It provides wavelength-selectable output using a fixed 10 or 20 nm FWHM bandwidth.

What wavelength range does TLS-Blue cover?

Depending on configuration, TLS-Blue can provide tunable output across selected VIS, IR, SWIR, or custom ranges within the overall 410-1700 nm TLS platform.

What bandwidth does TLS-Blue provide?

TLS-Blue uses a fixed 10 or 20 nm FWHM bandwidth, selected according to the system configuration.

What is the difference between TLS-Blue and TLS-Red?

Both systems provide wavelength-selectable picosecond output. TLS-Blue uses a fixed 10 or 20 nm bandwidth, while TLS-Red allows the spectral bandwidth to be adjusted.

How do I choose a TLS-Blue configuration?

Start with the required wavelength range, fixed bandwidth, optical power, pulse width, repetition rate, timing requirements, and application. RPMC can then help narrow the available supercontinuum source and wavelength-selection configurations.
