Laser-source fundamentals

How an Er:Glass source forms a short pulse.

Energy is stored in the erbium-doped glass gain medium and released as a short optical pulse when the passive Q-switch changes the resonator loss. The resulting pulse energy, width, beam divergence and repetition rate are interdependent design parameters—not independent settings to optimise in isolation.

01 / GAIN MEDIUM

Er:Glass

The active glass stores pump energy and provides the 1535 nm laser transition.

02 / PULSE FORMATION

Passive Q-switch

Supports compact pulsed operation without an externally driven Q-switch.

03 / OUTPUT OPTICS

Beam control

Output optics set the delivered beam geometry for the host optical path.

04 / PACKAGE

Design-in reference

Mounting, connector and aperture details must follow the selected model drawing.

Selection knowledge

Four parameters that determine whether a source will integrate well.

A source should be evaluated as part of the complete optical and electrical system. These inputs help define the initial model shortlist and the engineering questions for sample testing.

01 / ENERGY

Pulse energy

Pulse energy sets the optical energy available per emission. Select it against required system signal margin, receiver sensitivity, optical losses and the final safety assessment.

02 / DIVERGENCE

Beam footprint

Divergence controls how rapidly the beam expands. A host expander, aperture and alignment tolerance all influence the delivered footprint.

03 / REPETITION

Measurement cadence

Repetition rate must match acquisition timing, thermal budget and host processing. The 40 µJ model is specified at 1000 Hz; other listed models are 1–10 Hz.

04 / PULSE WIDTH

Temporal resolution

Shorter pulses can support time-of-flight resolution, but the full system response also includes detector, electronics, timing and signal-processing limits.

Added beam diameter ≈ θ × R

For small angles, use full-angle divergence θ in radians and propagation distance R. Include the source’s initial beam diameter, host optics and alignment tolerance in the detailed model. Confirm the divergence definition in the selected model’s specification.

Application solutions

1535 nm pulsed sources for civil, industrial and scientific instruments.

Application fit depends on pulse energy, divergence, repetition rate, the host optical path and receiver architecture. Representative system testing is recommended before design release.

Mechanical & electrical integration

Resolve the optical, electrical and mechanical interfaces before freezing the enclosure.

A laser source is only one part of the final instrument. Use the model-specific drawing and pinout as the integration baseline, and validate the assembled system including optics, mounting, cabling, supply stability and operating environment.

OPTICAL PATH

Aperture & alignment

Protect the output aperture, maintain clear aperture and control alignment with the host optical axis.

POWER

Source supply

The published source specification lists <2 V supply. Confirm start-up, drive current and grounding in the selected datasheet.

MECHANICAL

Mounting datum

Use the model drawing to locate fastening points, keep-out zones and thermal interfaces.

VALIDATION

System test

Test the finished host, not just the bare source, for optical performance and safety compliance.

Pre-sales FAQ

Clarify the design inputs before requesting samples.

These answers provide a practical starting point for source selection and quotation. Exact interfaces, acceptance criteria and drawings are confirmed for the selected model.

How should I choose between 40 and 500 µJ?

Start with the system’s optical link budget, receiver sensitivity, desired signal margin, host-optics transmission, range or sensing requirement and thermal/electrical limits. Higher pulse energy is not automatically the correct answer; the delivered beam, measurement cadence and final system assessment matter together.

Which models have 1000 Hz repetition rate?

The published 1535-LXER040 specification lists 1000 Hz. The 100–500 µJ models listed on this page are specified at 1–10 Hz. Confirm the required operating mode and duty cycle in the selected product datasheet.

Can you supply mechanical drawings and interface information?

Yes. Request the model-specific technical specification, mechanical drawing and available interface documentation during the quotation or sample-evaluation stage. These documents should be used as the design baseline rather than generic category-page values.

What does beam divergence mean for integration?

It describes the angular spread of the delivered beam. It influences the beam footprint, downstream aperture sizing and alignment tolerance. Host optics may further shape the beam, so calculate the complete optical path and verify it during system testing.

Can the source be customised?

We can evaluate OEM requirements for mechanical interface, electrical connection, optical configuration and programme documentation. Feasibility depends on the requested performance, production volume, validation scope and the final host application.

What information is needed for a sample recommendation?

Provide the target application, required pulse energy or signal margin, operating repetition rate, host optical layout, available space and mass, supply conditions, expected temperature range, expected quantity and target validation date.

Is the laser source itself the final certified product?

No. The source is an OEM component. The final instrument must be assessed in its completed optical, electrical and operating configuration against the applicable product and laser-safety requirements.
